To identify the properties that justify each step in the expression:
- Line 1: (8x + 6) + 5x
- Line 2: (6 + 8x) + 5x
- Line 3: 6 + (8x + 5x)
- Line 4: 6 + 13x
Let's identify the properties used:
Line 1 to Line 2:
- Step: (8x + 6) + 5x → (6 + 8x) + 5x
- Property Justified: Commutative Property of Addition
- This property allows us to change the order of the addends. Here, you switched the position of 6 and 8x.
Line 2 to Line 3:
- Step: (6 + 8x) + 5x → 6 + (8x + 5x)
- Property Justified: Associative Property of Addition
- This property allows us to group the addends in a different way. In this case, you grouped 8x and 5x together while keeping 6 at the front.
Summary:
- From Line 1 to Line 2: Commutative Property of Addition
- From Line 2 to Line 3: Associative Property of Addition
