Jill baked Ask Your Teacher dozen carrot muffins for a bake sale. Mike baked Ask Your Teacher dozen apple muffins. How many dozens of muffins were baked in all?

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

regards,  

mrb
