Answer:
19c + 30
Explanation:
Distributive property : a(b+c) = ab + ac
Explanation : simply multiply the value on the outside of the parenthesis by both the values on the inside of the parenthesis.
Here we have 1(19c + 30)
To distribute, we multiply 1 by both 19c and 30
1 x 19c = 19c
1 x 30 = 30
We're left with 19c + 30
