Question

Simplify -3 (n - 7) using the distributive
property

Answer 1

−3n + 21

Explanation:

This is the answer because:

1) You have to distribute everything from outside of the parenthesis to the inside

2) -3 times n is -3n

3) -3 times -7 is 21

4) Therefore, the answer is −3n + 21

Hope this helps!

Answer 2

-3n-+21

Step-by-step explanation: 1. Get rid of the Parenthesis , so times -3 by what’s inside

2. If you multiply -3 by n you get -3n

3. if you multiply -3 by -7 you get 21 , you get a positive because a negative times a negative is a positive

4. so now you have -3n + 21 you don’t add these because -3n has a variable and 21 doesn’t have a variable , and if 21 did have a variable it would need to also be n
