Answer:

Incorrect/No

Explanation:

7x2=14

-7x2=-14

Follow the below guidelines:

  • A positive number times a positive number is a positive number
  • A negative number times a positive number is a negative number
  • A positive number times a negative number is a negative number
  • A negative number times a negative number is a positive number

Looking at the last one, we see that -2x-7=14, a positive number

Hope this helps!
