X=40 degree is the correct answer
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
It depends on the shape it may be rotation
-11+9= 5t
-2=5t (divide both sides by 5)
t= -2/5
(Mark me the brainliest if this has helped )
First you subtract 25 from 5 which equals 20 then you multipliy 4 to 20 and you get 80...so 80 is your solution.
