Answer:
18m + 45n + 90
Step-by-step explanation:
You have to multiply whatever is inside the parentheses to the thing outside of it
like 2 x 9 is 18 so 18m
5 x 9 = 45 so 45n
9 x 10 = 90 so 90
Answer:
18m+45n+90
Step-by-step explanation:
Multiply 9 by each term
9*2m=18m
9*5n=45n
9*10=90
since there are no like terms you don’t do anything.
