Hypotenuse of the triangle distance points (-4,4) and (-2,2) ​

Solve the system of equations. y= 2x y= x^2 - 15

What are the sotions to the quadratic equation 9x^2=4

Given right triangle a w/a hypotenuse length of x+4 and a leg of x, and right triangle b, w/ a hypotense length of 3y and a leg length of y+4 for what values of x and y are the triangles congruent by hl?
