lol part b is tripping me up a little but i can help you with part c! another way to phrase part c is which expression will determine the money Cory will earn for trimming hedges. So if Cory earns $9 per hedge, which expression determines how much he will earn for all the hedges?

for part B this is the answer There are 2 terms in this expression which is 9 and 20. $20 is one term and $9 is the second term. The 20 is the number that represents the money that Cory earns for each lawn mowed that is how I know that is one term. The second term which is 9 represents the money earned for every hedge trimmed that is how I know that.
