-19ab + 2ab^2 +7
Step-by-step explanation:
all you do is combine the like terms. and the omly like terms are -10ab and -9ab. 2ab^2 is not one of the like terms simply because of that ^2.
The first one = 60.3 so it can’t be that one.
the second one = 34.5 so not that one either
the third one = 60.3
and the last one = 28.3
