the coefficients are the numbers being multiplied by the variables ;)

Answer 5

the variables are the unknown values (letters)

Answer 6

so the coefficents are just 20 and 9?

Answer 7

Answer 8

so for part b is there only two terms in the expression? And how do you know if theres only 2? thats what part b is asking lol

Answer 9

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?

Answer 16

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.
