To justify the steps between the lines, we can identify the properties used:
Line 1 to Line 2: **Commutative Property of Multiplication**
(This property states that the order in which two numbers are multiplied does not affect the product. Thus, (2 + x)x can be rewritten as x(2 + x).)
Line 2 to Line 3: **Commutative Property of Addition**
(This property states that the order in which two numbers are added does not affect the sum. Hence, (2 + x) can be rewritten as (x + 2).)
So, the justifications are:
**Line 1 to Line 2:** Commutative Property of Multiplication
**Line 2 to Line 3:** Commutative Property of Addition
Line 1 to Line 2: **Commutative Property of Multiplication**
(This property states that the order in which two numbers are multiplied does not affect the product. Thus, (2 + x)x can be rewritten as x(2 + x).)
Line 2 to Line 3: **Commutative Property of Addition**
(This property states that the order in which two numbers are added does not affect the sum. Hence, (2 + x) can be rewritten as (x + 2).)
So, the justifications are:
**Line 1 to Line 2:** Commutative Property of Multiplication
**Line 2 to Line 3:** Commutative Property of Addition
