It is impossible to determine which is greater from the information given

(A) and (B) are equal

(A) is greater

(B) is greater

**Correct answer:**

(A) and (B) are equal

(A) and (B) are equivalent variable expressions and are therefore equal regardless of the values of and .

### Example Question #7 : How To Find The Distributive Property

Simplify the below:

**Possible Answers:**

**Correct answer:**

In order to simiplify we must first distribute the -2 only to what is inside the ( ):

Now, we must combine like terms:

This gives us the final answer:
