x = 2
if sr parallel to ba then the sides bc and ac are in proportion, that is
= ← substitute values
= ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
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
