Answer:
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34
Step-by-step explanation:
At the first down, the net yardage of the football team was of 0.
After the first play:
Lost 15 yards, so the change in yards is:
0 - 15 = -15
After the second play:
Lost 19 yards, so the change in yards is:
-15 - 19 = -(15 + 19) = -34
The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34
