Use the Pythagorean theorem

to find the missing side length of a right triangle
In this case, after you plug in the given numbers your equation is

Then, Just solve that equation for y.



y = 16
So the answer is B, 16 cm.
I hope this helps, please feel free to ask questions if you're still confused :)
(5x+2)(8x^2+1) is the answer when factored.
So the x intercepts are going to be at the places where y = 0 so you can just read that off and get (-2,0) and (3,0). Hope this helps :)
All you have to do is make the fraction of it which is 4/30. Then simplify to 2/15 which is your answer.
Slope intercept form is y=5/3x+5
The slope is 5/3
