Answer: \(\sqrt{5}\)
Explanation:
To solve this, first check to see if the radicands are simplified.
Radicands are the expressions inside the radical symbol.
In this case, we have "20", "45", and "5".
To simplify a radicand, reduce the number to its factors:
20 = 2 * 2 * 5
45 = 3 * 3 * 5
5 = 5
Any factor that appears twice can be simplified by removing it from the radicand and placing it on the left of the radical. For example:
\(\sqrt{90} = \sqrt{3 * 3 * 5 * 2} = 3\sqrt{5 * 2}\)
The simplified variant of the square root of 90 is three times the square root of 10.
So, using this method, the simplified versions of the square roots of 20 and 45 are:
\(2\sqrt{5}\) and \(3\sqrt{5}\).
Substituting these in the equation:
\(-2(2\sqrt{5}) + 2(3\sqrt{5}) -\sqrt{5}\)
You can multiply the coefficients of the radicals like normal integers -
\(-4\sqrt{5} + 6\sqrt{5} -\sqrt{5}\)
You can treat the square root of 5 as a variable and subtract the coefficients.
-4x + 6x - x = x
The answer is the square root of 5.

Q: Read the following excerpt from The Princess and the Goblin by George Macdonald. Then, answer the question that follows.
Perhaps you will wonder how the princess could tell that the old lady was an old lady, when I inform you that not only was she beautiful, but her skin was smooth and white. Her hair was combed back from her forehead and face, and hung loose far down and all over her back. That is not much like an old lady—is it? Ah! but it was white almost as snow. And although her face was so smooth, her eyes looked so wise that you could not have helped seeing she must be old. The princess, though she could not have told you why, did think her very old indeed—quite fifty, she said to herself.

What did the Supreme Court ruling in Brown vs. the Board of Education fail to make clear?
A( which schools needed to comply with the court's order
B( how school segregation violated the U.S. Constitution
C( why schools needed to change from segregated to integrated
D( how to ensure that the court's order was followed
Answers
Answer:
D. How to ensure that the court's order was followed
Explanation:
In 1954, Brown vs. the Board of Education, the Supreme Court ruled that state rules that required racial segregation in public schools were illegal. This put an end to segregation in the United States. However, the court's order failed to give clear instructions on how to make sure it was followed, which led to years of court and political fights over integration.
Some southern states even went as far as implementing "massive resistance" policies, attempting to circumvent the integration order. The resistance led to prolonged court battles and protests, further delaying the full implementation of desegregation in schools. Additionally, the ruling sparked a broader civil rights movement, inspiring activists to fight for equal rights in other areas of society beyond education.

Animals can be entertaining, caring, and helpful. Some animals assist people with day-to-day activities while others are members of the military or a police force. After reading these passages, write an opinion about how you think animals could be useful in a community, a school, or a place of work. Be sure to state your opinion and support it using information presented in both passages. [Word Limit-225]
Before you begin planning and writing your opinion, read the two passages [Checkout the Sources in the Attachment]
1. “Animal Helpers”
2. “Military and Police Force Animals”

Answer:
Animals can be useful in a community and a school because when your reading animals can't tell you that you mispronounced a word. In fact you will most likely go back over that word and say it correctly. Animals can also be useful because whenever you need a little brain break animals can help entertain you and you can help entertain them and give them a good workout.
Explanation:
I don't know if your supposed to write an essay but yeah...
My opinion is that animals can provide an invaluable service to a community, school, or place of work. For example, in the first passage it mentions how animals are used as therapy and emotional support for people with disabilities or mental health issues. This illustrates how animals can be incredibly helpful when it comes to providing comfort and companionship to those who need it most. Additionally, the second passage talks about how police forces use dogs for search and rescue missions which demonstrates their ability to help keep people safe in dangerous situations. Furthermore, schools could benefit from having animal-assisted activities such as pet therapy which would give students another outlet for stress relief while also teaching them responsibility. All these examples show that animals have numerous potential uses that could make communities more efficient

Answers
The effect of the phenomenon observed by the student where one hemisphere of Earth tilting toward the flashlight while the other hemisphere tilted away, is the changing of Earth's seasons.
How does the Earth's seasons change?The axis of the Earth continues to be tilted at an inclination of around 23.5 degrees as it revolves around the sun. This means that at certain times of the year, one hemisphere of the Earth is inclined toward the sun, while the other hemisphere is slanted away.
The hemisphere that initially inclined toward the sun progressively tilts away, and vice versa, as the Earth continues its circle around the sun. As a result, each hemisphere sees differing quantities of sunshine and fluctuations in temperature, precipitation, and weather patterns, which results in the seasons changing from summer to fall to winter to spring.

Why might a professional (paid) army be less effective than a volunteer army?
Answers
Answer:
Voluntary military is better because armies are only justified when they defend the country from imminent outside threat. Paid armies are easily abused as the drafted ones. They hire people in peace time, train them, and lock them to wars they never wanted to fight. If they are able to leave when such wars broke out, the country would never get into those wars.

EMERGENCY! Need a speech on evolution by natural selection - a rough draft
Answers
Answer:
Evolution is regarded as the development or the act of uprising the status of any thing
in ur context evolution on natural selection means the development of the natural resources proper utilisation Nd making it to sustain
if natural evolution occurs then in return we will be helped as well as world would be a better place to live keeping all these pollutions aside
Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others. Individuals with adaptive traits—traits that give them some advantage—are more likely to survive and reproduce. These individuals then pass the adaptive traits on to their offspring. Over time, these advantageous traits become more common in the population. Through this process of natural selection, favorable traits are transmitted through generations.
Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.
Darwin chose the name natural selection to contrast with “artificial selection,” or selective breeding that is controlled by humans. He pointed to the pastime of pigeon breeding, a popular hobby in his day, as an example of artificial selection. By choosing which pigeons mated with others, hobbyists created distinct pigeon breeds, with fancy feathers or acrobatic flight, that were different from wild pigeons.
Darwin and other scientists of his day argued that a process much like artificial selection happened in nature, without any human intervention. He argued that natural selection explained how a wide variety of life forms developed over time from a single common ancestor.
Darwin did not know that genes existed, but he could see that many traits are heritable—passed from parents to offspring.
Mutations are changes in the structure of the molecules that make up genes, called DNA. The mutation of genes is an important source of genetic variation within a population. Mutations can be random (for example, when replicating cells make an error while copying DNA), or happen as a result of exposure to something in the environment, like harmful chemicals or radiation.
Mutations can be harmful, neutral, or sometimes helpful, resulting in a new, advantageous trait. When mutations occur in germ cells (eggs and sperm), they can be passed on to offspring.
If the environment changes rapidly, some species may not be able to adapt fast enough through natural selection. Through studying the fossil record, we know that many of the organisms that once lived on Earth are now extinct. Dinosaurs are one example. An invasive species, a disease organism, a catastrophic environmental change, or a highly successful predator can all contribute to the extinction of species.
Today, human actions such as overhunting and the destruction of habitats are the main cause of extinctions. Extinctions seem to be occurring at a much faster rate today than they did in the past, as shown in the fossil record.
