Find the area of this triangle. Round to the nearest whole number. A. 35 B. 42 C. 84 D. 70

35 units²

Step-by-step explanation:

Using the triangle area formula:

0.5×14×5=

35 un²

You can consider lost yards as negative, and gaines yards as positive. So, if they lost 9 yards and then gained 9 yards, the expression is

-9+9=0

This means that the team is exactly where it started (which maked sense, because they lost exactly as much as they gained.

If they gained first and lost then, it wouldn't change a thing: you'd have

9-9=0

and so the team is always where it started.
