Answer:
90x + 4
Step-by-step explanation:
This is the answer because:
1) You cannot add all the numbers because there are only two like terms, 35x and 55x
2) Since we only have two like terms, we have to add them. We will get 90x
35x + 55x = 90x
3) 4 is not a like term since there is no x next to it; therefore the answer is
90x + 4
Hope this helps!
