answer is D

each triangle rotation rotates at a 60 degree angle for c and d to equal d and e c and d would have to rotate 60 degrees. and 60 multiplied by 4 is 240 so you just move c and d's triangle four triangles to the right/four triangles clockwise and after the four triangle rotation you would get G and B

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
