which set of numbers could represent the lengths of the sides of right triangle

A. 7,9,11

B. 12,18,22

C. 10,15,20

D. 8,15,17

We have to use Pythagorean Theorem to solve this. We square the two smallest sides, then add. If the sum is the square of the largest side, then it's our answer.

A. 7, 9, 11

49 + 81 = 130 ≠ 121

B. 12, 18, 22

144 + 324 = 468 ≠ 484

C. 10, 15, 20

100 + 225 = 325 ≠ 400

D. 8, 15, 17

64 + 225 = 289 = 289

So, our answer is D

y= -

the square root of what number? if you add that, then someone will probably answer the question.
