IV) 9,12,15
Step-by-step explanation:
Pythagorean Triples are when the numbers can be simplified into 3,4,5. This being said, we need to see if all the numbers can be multiplied by the same number to get a new Pythagorean triple.
In this case, the answer would be IV. This is because when multiplied by 3 all three numbers (3,4,5) turn into 9,12,15
