Answer 1

The expression with addition that shows the changes in yards on the first two downs is -(15 + 19) = -34

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
