Valerie Downs · Answer 2

Answer

Distributive Property.

Step-by-step explanation:

First you solve for the first equation by multiplying 2 by 18 which is 36. Then 3 times 18 which is 54. Then you add them together to get 90.

Next you solve for the second equation by multiplying 5 by 18 which is 90.

Both of these equations are solved by the distributive property because your distributing the number outside of the parenthesis.
