Answer: 5(f+7)
Step-by-step explanation: I know you didn't ask for an explanation but here:
First what you want to do is find what both terms have in common, the LCM, (least common multiple), is the only thing common between them, which is 5, so divide 35 by 5, which is 7, and since you divided by 5, you put it outside, and put f and 7 together.
