Answers
Answer: Choice A is correct
Explanation:
The LCM of the coefficients 14 and 16 is 112 because (14*16)/2 = 112. We multiply the values and divide by the GCF 2.
The 'a' terms are \(a^5\) and \(a^3\). We pick the one with the largest exponent when forming the LCM. Go for the smallest exponent when finding the GCF. Similar situations occur with the b and c terms as well.
So that's how we end up with \(112a^5b^4c^2\) as the LCM.
Side note: Choice D is the GCF of the two given expressions.

A store sells two kinds of candles,scented candles and unscented candles. The candles burn at different rates which kind of candle burns more in one hour? How much more per hour? The scented one burns 1/8inch an hour 1/4 hour and the unscented one burns 1/9 inch in 1/3 hour. SHOW WORK!!!!
Answers
Step-by-step explanation:
The first thing we must observe is that the hourly rate for each candle is:
scented candles:
(1/12) / (20/60)
Simplifying:
= (1/12) / (10/30)
= (1/12) / (5/15)
= (1/12) / (1/3)
= (3/12)
= (1/4) inches / hour
Unscented candles:
(1/6) / (30/60)
Simplifying:
= (1/6) / (15/30)
= (1/6) / (3/6)
= (1/6) / (1/2)
= (2/6)
= (1/3) inches / hour
Answer:
The unscented candles burn faster at a rate of:
(1/3) inches / hour.
Answer:

Answers
Answer:
Step-by-step explanation:
1. 3x + 2y - 2x + y + 12 is equivalent to x + 3y + 12
2. 4y + 3y + 3x - 6y - 10 - 2 is equivalent to 3x + y - 12
3. x + 3y + 2x - 3x + 7 + 5 is equivalent to 3y + 12
4. I do not know unfortunately
Answer:
See attached image
Step-by-step explanation:
To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression
I will tell you how to solve one of the more complex expressions; the technique is the same for the rest
Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2
To simplify,
group like terms:
=(4y + 3y - 6y) + 3x +(-10 -2)
= y + 3x - 12
Rewriting with x before y gives
3x + y - 12
and there is a matching 3x + y - 12
4y + 3y + 3x - 6y -10 - 2 ⇔ 3x + y - 12
The solution is in the attached image

Which product is negative?
Answers
Answer: The Answer to your question would be D-Number 4
Step-by-step explanation: A Negative Number Multiplied by a Negative number is Positive. Each negative number cancels out the other. In A., there are 2 negatives, and 2 positives, so it would be a Positive. In B., There are 3 negatives, but there is a 0, and anything times 0 is 0, And 0 is neither negative nor positive. In C., All of the numbers are negative, so they cancel each other out, and make a positive. Lastly, In D., there is one positive, and three negatives. 2 Negatives cancel eachother out, and there is one negative and one positive remaining. A positive multiplied by a negative is also negative. So then the negative multiplied by the positive is negative.

The linear function graphed below represents the height of a stalk of corn since a farmer began using a new fertilizer. What is the initial value?
A graph titled Height of a Stalk of Corn has Number of Days Using New Fertilizer on the x-axis and Height (feet) on the y-axis. Points are at (3, 10), (4, 12), (5, 14), and (6, 16).
Answers
Answer:
The initial value is 4
Step-by-step explanation:
the linear equation is 2/1 or 2. the equation is y = 2x + 4. In other words every time it rise 2 the line move the right 1. We just have to retrace our steps and since 3 - 3 = 0 we have to retrace it 3 times and 6 times on the y axis which gets us 4.

Megan and Desmond each added the same amount of water to their aquariums. Megan mixed 5 mL of a chemical solution with every gallon of water for her aquarium. Desmond mixed 8 mL of the chemical solution with every 2 gallons of water for his aquarium.
Which of these statements is true?
Answers
Answer:
i think it is the second one
Step-by-step explanation:
The statement "Megan added more chemical solution to her aquarium than Desmond did" is true.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
To compare the amount of chemical solution used by Megan and Desmond, we need to convert their rates to a common unit.
Let's convert Megan's rate to mL per 2 gallons by using proportions:
5 mL / 1 gallon = x mL / 2 gallons
Multiplying both sides by 2, we get:
10 mL = x
So Megan added 10 mL of chemical solution per 2 gallons of water.
Desmond's rate is already given as 8 mL per 2 gallons of water, so we can compare their rates directly.
Since 10 mL is greater than 8 mL, Megan added more chemical solution to her aquarium than Desmond did.
Therefore, the statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
