Answer: 80 - 8c
Explanation:
Distribute the outter number into the parenthesis. After distributing you’ll want to multiply the outter number with the numbers that were in the parenthesis individually.
8 • 10
8 • -c
Now find the sum for each then combine like-terms.
8 • 10 = 80
8 • -c = -8c
Remember that a negative times a positive will remain a negative!! Since there are no like-terms we end up with the following equation, 80 - 8c
