Im not sure. ( i cant go back to a question btw)
IF U KNOW MATH PLS HELP

I feel like it would be B

Step-by-step explanation:

I  dont like to divide so i basically multiply all the answer choices for questions like these! I choose B becuase A is 3 pigeons short. while B would have room or more pigeons the others are unreasonable cause there would be Way too many cages

i am unable to solve this problem

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

mrb
