$\boxed {9x^{2} + 28x-32}$

9x * x = 9x $^{2}$

9x * 4 = 36x

-8 * x = -8x

-8 * 4 = -32

Combine like terms.

36x - 8x = 28x

We are left with.

9x^2+28x-32

The answer would be the fourth option.

A pool company is creating a blueprint for a family pool and a similar dog pool for a new client. Which statement explains how t

Xelga [282]

Answer: B.

Step-by-step explanation: These are the multiples of 15 but what you are probably asking or what are the factors of 15. If ABCD and EFGH are similar, then you should be able to line up corresponding points (for example, A corresponds to E, B corresponds to F). if they're different sizes, you should then dilate one of them so that they are the exact same size.
