Geometry: Express the area of each figure as a monomial. I need help with this, anyone?

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

X-intercept=-5 y-intercept=2 the equation of the line is
