Which equation demonstrates the distributive property?

That would be d.

Remember, the distributive property is a(b+c) = ab +ac!

Hope this helps.

If you have any questions, place it in the comment section below.

The distributive property is when you use one number  to multiply the numbers inside the parentheses. 

As well as, a(b+c) = ab +ac!

Let me show you an example! 

9(3+7)

Using 9 I would first multiply 3 and then seven so we would get. 

27+63= 90

Now let's use our knowledge of this on your question!

We just learned above that the distributive property is when you use one number to multiply the numbers in the parentheses. If we look at our answer choices the best answer represented from what we learned is D,  because you also have a(b+c) = ab +ac as well as a single number that will be used to multiply the numbers inside the parentheses which is represented by  a(b+c)

D, is the correct answer because you are using one number to multiply the numbers inside the parentheses. 

Thus, our answer to this question would be D.
