J(x) = 12(3x - 5)
j(x) = 36x - 60

Answer:

Step-by-step explanation:
Think of this situation as a number line in which the team starts at 0 yd.
Gaining yards is the positive direction and losing yards is negative.
Start at 0 yd and go 5 yd to the right. You are at +5.
Then go 7 yd left. You end up at -2.
+5 – 7 = -2

There are 21 people, everyone hugs each other, but the person hugging cant hug themself, so (21*21)-21
(21*21) -21 = 441
441-21=420
