Answer:
(C)
Step-by-step explanation:
In order to find whether the given side lengths form a right triangle or not, we must show that it satisfies the Pythagoras theorem.
A.
, 10 and 116
According to Pythagoras theorem,
⇒![(116)^2=4+100](https://tex.z-dn.net/?f=%28116%29%5E2%3D4%2B100)
⇒![13456=104](https://tex.z-dn.net/?f=13456%3D104)
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
B. 3,6 and 8
According to Pythagoras theorem,
⇒![(8)^{2}=(3)^2+(6)^2](https://tex.z-dn.net/?f=%288%29%5E%7B2%7D%3D%283%29%5E2%2B%286%29%5E2)
⇒![64=9+36](https://tex.z-dn.net/?f=64%3D9%2B36)
⇒![64=45](https://tex.z-dn.net/?f=64%3D45)
which does not satisfy the condition, therefore these side lengths do not form a right triangle.
C. 30, 40 and 50
According to Pythagoras theorem,
⇒![(50)^{2}=(30)^2+(40)^2](https://tex.z-dn.net/?f=%2850%29%5E%7B2%7D%3D%2830%29%5E2%2B%2840%29%5E2)
⇒![2500=900+1600](https://tex.z-dn.net/?f=2500%3D900%2B1600)
⇒![2500=2500](https://tex.z-dn.net/?f=2500%3D2500)
which satisfies the condition, therefore theses side lengths form right triangle.
The correct answer would be:
-2xy + x^2y - 2xy^2
