Will mark BRAINLIEST for 5 and 6

  5. yes

  6. no

Step-by-step explanation:

5. yes

You know this because you're familiar with the first few Pythagorean triples:

   (3, 4, 5), (5, 12, 13), (7, 24, 25), ...

If you're not, you can use the Pythagorean theorem to check. The sides will form a right triangle if and only if they satisfy the Pythagorean theorem.

  13^2 = 12^2 +5^2

  169 = 144 + 25 . . . . . . true

6. no

Your knowledge of numbers tells you that these numbers cannot satisfy the Pythagorean theorem.* The sum of an even and and odd number cannot be even. (The square of a number has the same parity as the number itself.)

* Thanks to , I recently figured out that you can apply a parity test to candidates for right triangle sides. The number of odd-length sides must be even. There cannot be a right triangle with integer side lengths, only one of which is odd.
