answer TRUE because they would make a triangle
The answer is -3 because mathematically -15 divided by 3 equals -3
As a rule , - times - = + and - times + = -

Therefore the correct answer to the question is 2m squared n
An equation says that two things are equal. It will have an equals sign "=" like this:
