Question

Which expression is equivalent? −9(−2x − 3) A) 18x + 27 B) 18x − 27 C) −18x + 27 D) −18x − 27

Answer 1

Simplify `-9(-2x-3)`

Explanation:

All you have to do is use the distributive property which means -9 is multiplied to -2x and -3. Thus arriving at `18x+27`. The answer is A.

Answer 2

A) `18x+27`

Explanation:

Let's start by taking the expression we're given:

`-9(-2x-3)`

What we can do to simplify this business is distribute the `-9` to both terms. Recall that when we multiply two negatives, the result is positive.

This gives us

`18x+27`

Which is choice A.
