The completed statements would be:
- After applying the distributive property, Gustavo's expression was
- After he used the commutative property, his expression was
Let's go through the steps to solve the problem presented in the image.
Step 1: Distributive Property
The distributive property states that
Applying this to Gustavo's expression
, we get:
So, after applying the distributive property, Gustavo's expression was 9w + 45 .
Step 2: Commutative Property
The commutative property of addition states that the order of addition does not change the sum. This means
Applying this to the expression
we can write it as
without changing its value.
So, after using the commutative property, his expression was
