Answer:
-4x+28
Step-by-step explanation:
You have to distribute the -4 into the x and the -7.
You would start by multiplying the -4 by the x, which gives you -4x.
Then, you would multiply -4 by -7, which would give you a positive 28. Remember, when adding and multiplying, two negatives equal a positive, two positives equal a positive, and a negative and a positive equals a negative.
