Answer:
GAE= 77
Step-by-step explanation:
so, we need to find what GAE equals
and we have what GAM equals and GAE+MAE=GAM
so we can add them and set them equal!
x^2+5x+4=13x+24
move all terms to the left side and set equal to zero!
x^2+18x+28=0
(we can use a diamond to solve this too) solve how ever you want to find x
x=10, -2
substitute the x in the GAM equation and you get 10^2+5(10)+4=154
then we can subtract MAE from GAM
7(10)+7=77
154-77=77
so GAE should be 77
