OB) 5+ 6 - 6
C) -1 + 8
D) 13 – 6

9X2-6

Step-by-step explanation:

9X2-6 because if we add 5 and 4 we get

so it is 9x2-6

linear pair postulates

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
