Use properties of operations to write two equivalent expressions for 13(4 + x). 1. Explain how to distribute the 13 to the terms inside the parentheses, then do the distribution. Use multiplication to simplify the result.

2. Write another equivalent expression by using the commutative property of addition.

1.

13 (4 + x)

13(4)    13(x)

52+13x

Explain:  To distribute 13 to the terms inside the parentheses, I would need to multiply 13 to each of the terms.

2.

52+13x= 13x+52

Step-by-step explanation:

1. Draw lines on top of the equation from 13 to 4 and 13 to x. Draw arrows from 13(4) to 52 and 13(x) to 13x.  This shows the distribution.
