Francois baked just enough cookies to fill all the orders at his bakery. while the cookies were cooling, a kitchen assistant knocked over a cooling rack and spilled 12%, percent of the cookies onto the floor. francois had to bake 36 more cookies to replace them. how many cookies were ordered in total?

1 is c

2 is a

3 is a

step-by-step explanation:

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
