Find the value of x.

The answer is 50 . I need to show equations and show my work

50

Step-by-step explanation:

80+2x=180

subtract 80 from both sides: 2x=100

divide both sides by 2: x=50

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
