Shaquille, Lyle and Amanda collects stamps. Shaquille has one-half the number of stamps that Lyle has. Amanda has two thirds as many stamps as Lyle. Together they have 364 stamps. How many stamps does Amanda own

112

Step-by-step explanation:

Shaquille number of stamps - x

Lyle - 2x

Amanda - 2/3(2x) = 4/3x

x+2x+4/3x=364 ->13x/3

x = 84

4/3(84) = 112 stamps

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
