Answer 1

Hello! The correct answer for you is D) -18x-1

Explanation:

So, let me explain. Do the following.

• −18x − 1
• 5 − 3(6x + 2)
• 5 − 18x − 6
• −18x − 1

Answer 2

Hi there! The answer is D) −18x − 1

To find our answer we need to work out the parenthesis (for instance possible by using rainbow technique):


`5 - 3(6x + 2) = \\ 5 - 3 * 6x - 3 * 2 = \\ 5 - 18x - 6 =`

Now collect the terms.

`5 - 18x - 6 = \\ - 18x - 1`

Hence, the answer is D) −18x − 1
