Answer:
16
Step-by-step explanation:
-8--------------------------0---------------------------8
imagine this is a straight line where you can measure the distances.
to get from -8 to 0 we have a distance of 8 units.
so, knowing this, now from 0 to 8 we have another distance of 8 units.
8+8=16
Distance is the absolute value, meaning that it'll always be positive.
