kipiarov [429]

Answer:

1. Commutative Property of Addition

2. Distributive property

Step-by-step explanation:

Given

Line 1:  4(8+9x)

Line 2:  4(9x+8)

Line 3: 36x+32

Required

Justify each step

From Line 1 to 2:

The property from Line 1 to 2 depicts a + b = b + a;

i.e.

4(8 + 9x) = 4(9x + 8)

This is referred to as Commutative Property of Addition

From Line 2 to 3:

The property here depicts a(b + c) = a * b + b * c

i.e.

4(9x + 8)  = 4 * 9x + 4 * 8

4(9x + 8) = 36x + 32

This is referred to as Distributive property
