Answer:
12
Step-by-step explanation:
The question is asking to find the absolute value of 8 plus the absolute value of -4.
The absolute value of a number is simply the distance that number lies away from 0 on the number line.
This means that the absolute values of both 8 and -4 is positive, because absolute value eliminates the direction that a point is in, so there is no negative.
So the question is asking what 8 + 4 is, which is 12.
The football team moved 8 yards forwards and then 4 yards back. In total, that would be 12 yards moved.
