Maria solved the equation.

What methods did she use and in what order did she use them?

PEMDAS maybe???

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

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
