A. R’ (0, 2), S' (3, 48), T' (36, 2)
B. R’ (0, 2), S' (18,8), T’ (36,2)
C. R’ (0, 12), S' (18,48), T’ (36, 12)
D. R’ (6,8), S' (9, 14), T’ (12,8)

the answer would be 7

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

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!

it would open into a square depending on the type of envelope i’m not sure about the second part
