Hello there, and thank you for posting your question here on brainly.
Short answer: -42
Why?
So, we have a negative number: -6. Before we do anything with that yet, we have to do the parenthesis first. The equation inside the parenthesis is 14 - 7, which is 7. Now, we have to multiply it by -6. All you have to do is multiply regularly, or ignore the negative sign. -6 * 7 ==> -42. -42 is the final answer.
Hope this helped you! ♥
