2(8 + h) The Distributive Property allows us to multiply any number/variable outside of the parenthesis by all numbers/variables inside the parenthesis.
For example; 2(1 + 2) 2(1) + 2(2) 2 + 4 6.
Let's try this with our current problem. 2(8 + h) 2(8) + 2(h) 16 + 2h (This is your simplified expression)
