The answer is A. Each time it is multiplied by a higher number so 1 x 2 = 2 . 2 x 3 = 6 . 6 x 4 = 24 . 24 x 5 = 120 . 120 x 6 = 720

Hey there.

8/9d = 28; multiply both sides by 9.

8d = 252; divide both sides by 8.

d = 31.5

I hope this helps!

Answer:

Step-by-step explanation:

Hello, please consider the following.

$(2x-2)^2 - (x+4)^2 \\\\=(2x-2-(x+4))(2x-2+x+4)\\\\=(2x-2-x-4)(3x+2)\\\\=\boxed{(x-6)(3x+2)}$

$(3x+4) (3x-4)\\\\=(3x)^2-4^2\\\\=\boxed{9x^2-16}$

Thank you.
