Example Question #1 : Distributive Property

Which of the following expressions is equivalent to the expression below?

Possible Answers:

Correct answer:

Explanation:

First, we can distribute the into the parentheses.

Now we can simplify the terms.

Subtracting a negative is the same as adding a positive.

Example Question #1 : How To Find The Distributive Property

Possible Answers:

Correct answer:

Explanation:

Using the distributive property, multiply 3 times each of the numbers in parentheses, then add both products:

The answer is 27.

Alternatively, add the two terms inside the parentheses and then multiply the sum by 3:
