The side lengths of a triangle are 5,3, and 4. Is this a right triangle?
A. No, because 3 + 4 + 5.
B. Yes, because 32 + 42 = 52
C. No, because 32 +42 + 52.
D. Yes, because 32 + 42 > 52.​

B

Explanation:

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
