What is the area of this triangle?
a. 17 m
b. 30 m
c. 60 m
d. 120 m

60m because you will need to multiply the base which is 12 times the height 5 and you will receive 60

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
