HELP NEEDED ASAP FOR 10 POINTS

Option D

Step-by-step explanation:

(10x + 13) + (12 + 9x) + ( 13x + 12) + 55 + 44 = 360

32x + 136 = 360

Subtract 136 from both sides;

32x = 224

Divide both sides by 32;

x = 7

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

you,

mrb

your answer is b.

x = 33.9
