Answer:
16z - 48
Explanation:
8(2z-6)
To do the Distributive Property, multiply the number outside of the parenthesis by each number inside the parenthesis, to get something like this:
8(2z) and 8(-6)
16z - 48
((If you get a positive number for the second number then it'd be 16z + 48 but since it's negative it's 16z - 48))
