At a football game, your team lost 55 yards on the first play and then 77 yards on the second play. which expression gives the total loss in yards?
-7+5
-5−(-7)
-5+(-7)
5+(-7)

The answer is the third one (C?) because if you started at 0, you are going below it since you are losing yards, causing you to have less and less yards. Adding two negatives gives you a lesser amount.

Number nine is f(x)= 40x : ) hoped i ya
