If ST=SV=90, TU=7x, and UV=x+84, what is the value of x?

i believe it's a.

i'm not sure on this one, most likely correct.

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
