Answer:
M+16m
Step-by-step explanation:
-9m+9 cancel eachother out because it is a negative and a postive value, so you would just put the variable. For 8m+8 it would be 16m because the sre both positive so you would add them like normal
Step-by-step explanation:
[tex] = ( - 9m + 9) + (8m + 8)[/tex]
[tex] = - 9m + 9 + 8m + 8[/tex]
[tex] = - 9m + 8m + 9 + 8[/tex]
= m + 17
hence m + 17 is the answer....
