Let's fill in the blanks based on the provided information:
- Distributive property: a(b+c) = ab + ac
- a(b+c) = ab + ac
- 4 (1+3) = 4(4) = 16
- 4(1) + 4 (3)
- 4 + 12 = 16
So, the complete filled in section would look like this:
Distributive property: a(b+c) = ab + ac
a(b+c) = ab + ac
4 (1+3) = 4(4) = 16
4(1) + 4 (3)
4 + 12 = 16
