im smart
Answer: 5mn + 5m + 4n + 4
because
2mn - 7mn = 5mn
5m = 5m
stays the same
4n = 4n
stays the same
2 + 2 = 4
if you put them toghether than you get:
5mn + 5m + 4n + 4
is equal to
2mn + 4n + 2 and 5m + 2 -7mn
5r-4 and r=-5 so it would be 5(-5)=-20, then -4 , so is is -24
Cross multiply
5/8 and 8/10
5x8=40
8x8=64
40 does not equal 64 so not proportional
