U
V
.

Find angle Z:

Angle Z = 180-113-42 = 25 degrees.

Since TUV is similar than one of the angles must also be 25 degrees.

The answer is A.

The Correct Answer is A

Step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
