Final answer:
The Texans gained a total of 9 yards after four runs in a football game by adding the yards gained and subtracting the yards lost.
Step-by-step explanation:
The question deals with calculating the total yards gained or lost by the Texans in a football game. To find the total, we simply add the yards gained and subtract the yards lost. Let's do the calculation step by step:
- Start with 15 yards gained.
- Subtract 7 yards lost (15 - 7 = 8 yards).
- Add 3 yards gained (8 + 3 = 11 yards).
- Subtract 2 yards lost (11 - 2 = 9 yards).
So, the total yards gained by the Texans after the four runs is 9 yards.
