Answer:
as that guy who commented said, its civil war amendments
Step-by-step explanation:
A triangle is scalene if all of its three sides are different (in which case, the three angles are also different). If two of its sides are equal, a triangle is called isosceles. A triangle with all three equal sides is called equilateral
So, let's solve all of them and see:
a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers
a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers
a * (-b) = a * (-b) ⇒ negative answer no matter what
a / (-b) = a / (-b) ⇒ negative answer no matter what
So the answer is:
<em>"None of the above"</em>.
