Answer:

The answer is A.

Explanation:

This is because if u do (4y+9)^2 this is equal to (4y+9)(4y+9). Now do 4y*4y to get 16y^2 because 2 of the same variables multipled make a 2 power. Next u do 4y*9 and 4y*9 both combined equal 72y and then 9*9 is 81. So now add from the one with the highest exponential variable value 16y^2+72y+81. This is answer A.
