For a long-term investment of five years, to make money you need to make at least what percent on your investment?

a. 4.2%
b. 5%
c. 6%
d. 8%

I just took the test, it was not B!!!

I think it could be C.6%

Step-by-step explanation:

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
