You can use the formula for finding the roots of a quadratic equation here.

The solution of given equation is: x = -1

The standard form is \(ax^2 + bx + c = 0\)

The solutions are:

\(x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)

To find the solutions, firstly we've to simplify it.

\(\sqrt{1-3x} = x + 3\\ \text{Taking square on both sides}\\ (\sqrt{1-3x})^2 = (x+3)^2\\ 1-3x = x^2 + 9 + 6x\\ x^2 + 9x + 8 = 0\)

Know that we took square.

Also know that \((\sqrt{1-3x})^2 = (-\sqrt{1-3x})^2 = 1-3x\\ \) This is the reason that both roots we will obtain won't belong to our quadratic equation we obtained. Thus, we will have to check which root is correct solution of the obtained quadratic equation.

Thus, we have a = 1, b = 9, c= 8, and thus,

\(x = \dfrac{-9 \pm \sqrt{81 - 32}}{2}\\\\ x = \dfrac{-9 \pm \sqrt{49}}{2}\\\\ x = \dfrac{-9 \pm 7}{2}\\\\ x = \dfrac{-9-7}{2} , \: x = \dfrac{-9+7}{2}\\\\ x = -8, \: x = -1\)

Putting x = -8 doesn't satisfy the equation. But x = -1 does.

Thus, the solution to the given equation is  x = -1

In order to find the magnitude of a vector with three components, use the formula:

|V| = sqrt(Vx^2 + Vy^2 + Vz^2)

where Vx, Vy, and Vz are the components of the vector along the x, y, and z axes respectively.

To find the magnitude, you need to square each component, sum the squared values, and take the square root of the result. This gives you the length of the vector in three-dimensional space.

Let's consider an example to illustrate the calculation.

Suppose we have a vector V = (3, -2, 4). We can find the magnitude as follows:

|V| = sqrt(3^2 + (-2)^2 + 4^2)

   = sqrt(9 + 4 + 16)

   = sqrt(29)

   ≈ 5.385

Therefore, the magnitude of the vector V is approximately 5.385.

Answer:

Explanation:

First, we can find the top and bottom smaller squares of the rectangular prism. Since we are working with a variety of rectangles, we only need to use the equation L×W.

To start with, let's multiply 2×3, which gives us 6, the surface area of both the bottom and top rectangles, so now we need to multiply it by 2 to account for both of them. 6×2=12

Now, we'll find the surface area of the bigger rectangles in the middle, which are 6 by 3, so again we will need to multiply length times width, then by 2 to count both rectangles. 6×3=18×2=36

Finally, we can find the surface area of the smaller rectangles in the middle, which are 6 by 2. 6×2=12, then multiply by 2 since there are 2 of those rectangles, 12×2=24

Now to find the total surface area, we need to add the gathered surface area from each shape, 12+36+24=72

Step-by-step explanation:

Given the expression

\(-3m - [2m + (5 - m)] + 7\)

Step one

Firstly we have to open the inner bracket we have

\(-3m - [2m + 5 - m] + 7\)

Step two

we proceed further by opening up the next bracket we have

\(-3m - 2m -5 +m+ 7\)

Step three

we then have to collect like terms of m and rearrange.

\(=-3m - 2m+m -5+ 7\\=-4m+2\\=2-4m\)

Answer:

p = 0, p = -7/3

Step-by-step explanation:

We are given the following equation:
3p² + 7p = 0

We want to solve the equation by factoring.

To factor, we want to look for a common term that we can pull out.

You may notice that both terms have 'p' in common, so we can pull out p from both terms.

This will then make the equation:

p(3p + 7) = 0

Now, we can use zero product property to solve the equation.

p = 0

3p + 7 = 0

Subtract.

3p = -7

Divide.

p = -7/3

Our answers are p = 0 and p = -7/3

The equation in slope intercept form to represent the equation is y = 2.5x

From the question, we have the following parameters that can be used in our computation:

The graph

On the graph, we have the following points

(x, y) = (0, 0) and (10, 25)

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

So, we have

y = mx + 0

y = mx

Next, we have

25 = 10m

This gives

m = 2.5

So, we have

y = 2.5x

Answer:

2(8a + 8)

Step-by-step explanation:

The easiest way to do this is to substitute a for a number. For example, let's just make things easy and make a = 1.

So, if a = 1, the expression 16a + 8 would be 16(1) + 8 = 24.

Let's find all the expressions that would also equal 24 if a = 24.

Plug in 1 for a in each of the equations. You will find that 2(8a + 8) will not equal 24 if a equals 1.

2(8a + 8)

2(8(1) + 8

2(8 + 8)

The relationship is proportional because, the points lie on a straight line that goes through the origin.

A relationship that is proportional has a straight line graph that must pass through the origin, whereby the constant of proportionality, k = y/x, where x and y are the variables of the proportional relationship.

An example of a graph that represents a proportional graph is shown in the attachment below. The graph is a straight line graph that passes through (0, 0), which is the origin. The constant of proportionality, k = 21/7 = 3.

Answer:

Step-by-step explanation:

(c) translate point D' to point A; ∠D'E'C' ≅ ∠BAC

To establish that ΔACB ~ ΔECD by the AA similarity postulate, we need to show that both pairs of corresponding angles are congruent.

Reflect ΔECD over segment AC: This means we mirror ΔECD across segment AC to create a new triangle, which we'll label ΔE'C'D'.

From the reflection, we can conclude that ∠ACB ≅ ∠E'C'D'. This is because the reflection preserves angles.

Now, we need to translate point D' to point A. Translation means moving an object without changing its shape or size. By translating D' to A, we create a new triangle, which we'll label ΔD'E'C'.

By translating D' to A, we can establish that ∠D'E'C' ≅ ∠BAC. This is because the translation preserves angles.

Therefore, based on the congruent angles we have established: ∠ACB ≅ ∠E'C'D' and ∠D'E'C' ≅ ∠BAC, we can conclude that ΔACB ~ ΔECD by the AA similarity postulate.

So, the correct answer is (c) translate point D' to point A; ∠D'E'C' ≅ ∠BAC.
