−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:

                                                 =

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.
