−9(−2x − 3) apply the distributive property to simplify the expression.

Step-by-step explanation:

Thinking process:

The distributive property states that:

You can multiply a sum by multiplying each addend separately and then adding the products.  

Let's look at the expression again:

−9(−2x − 3)

This is equals to =

The rule let's us distribute the -9 to both -2x and -3

This gives the two numbers:
