Solve (-2/5) (-1 1/4)

you need to give us more information since we can't answer

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

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

you,
