You now have several tools to use when solving for missing side lengths and angle measures decide which tool to use for each of the triangles below and solve for x if there is more than one solution find both name the tool you use.

after simplifying it i got: -36.25 as my answer. hope that !

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
