Answer:
It could be both 2 positives, or 2 negatives.
Step-by-step explanation:
This is because a negative times a negative is a positive, and a positive times a positive is a positive.
This is the Pythagorean theorem where the 2 legs of a triangle squared add up to equal the squared hypotenuse (a^2 + b^2 = c^2)
The equation would be
12^2 + 5^2 = x^2
144 + 25 = 169
The square root of 169 = 13
