Is this a right triangle?

Right Triangle

Step-by-step explanation:

I apologize for my original answer not living up to your expectations. I myself was a bit confused. But I will now provide an explanation. The way the image is tilted, it does not seem like a right triangle. But it is. The coordinates imply something else, but they are a tease. If you look upon the triangle in another way, it will look, or become, straight. Hopefully this explanation is helpful. Once again, I apologize.

5x+40

5(x + 8)

7x - 49

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
