The <em><u>correct answer</u></em> is:

7/3

Explanation:

The image, W'X'Y'Z', is larger than the pre-image WXYZ.  The new side given to us is 14, compared to the old side of 6; this gives us the ratio

14/6

This can be simplified by dividing top and bottom by 2:

(14÷2)/(6÷2) = 7/3

This is the scale factor.

The answer is D as shown in your image.

It's D because the new trapezoid is larger than the original, meaning the value of the dilation has to be larger than 1, and it's on the same side of C as the original, meaning the dilation has to be positive.

The answer is C 200

Because 10 / 200 = 0.05 * 100 = 5%

Factor the following quadratic equation; <br><img src="https://tex.z-dn.net/?f=12%20%7Bx%7D%5E%7B2%7D%20%20%2B%2022x%20-%2014" i

Answer:

2(3x + 7)(2x - 1)

Step-by-step explanation:

You can see it a little easier if you take out a common factor of 2

2(6x^2 + 11x - 7)

The 6 leaves you with a lot of factors, the 7 does not. It only has 2 factors.

Let 6 factor into 2 and 3 and the 7 into 7 and 1

2(3x - 1 )(2x + 7)

Now remove the brackets.

2(6x^2 + 21x - 2x - 7) This obviously does not work but we'll combine like terms anyway.

2(6x^2 + 19x - 7)

So we'll try it again

2(3x + 7)(2x - 1)

2(6x^2 + 14x - 3x - 7)    Looks like we have it.

2(6x^2 + 11x - 7)

So the right factors are

2(3x + 7)(2x - 1)
