The expression 72(x + y) is one way to represent the total number of tiles needed for 72 square feet.

Part C
Use the Distributive Property to write an expression that is equivalent to the expression you wrote in part B.

The expression using the Distributive Property would be:

72x + 72y

To use the distributive property and write an expression equivalent to 72(x + y), we will distribute the 72 to both terms inside the parentheses:

72(x + y) = 72 * x + 72 * y

Simplifying further:

72x + 72y
