Find all possible solutions for x and y such that △ABC is congruent to △DEF. △ABC: sides of length 18, 25, and 5x − 3.
△DEF: sides of length 25, 22, and 5 − y.

△ABC ≅ △DEF when x is
and y is

boxplot e is the answer

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

i don't think there is enough
