ALGEBRA Find x and the measure of each side of the triangle. GHJ is isosceles, with HG = JG, GH = x - 7, Gj=3x - 5,
and Hj = x - 1.

Apinhole camera is made out of a light-tight box with a piece of film attached to one side and pinhole on the opposite side. the optimum diameter d(in millimeters) of the pinhole can be modeled by d=1.9[ (5.5 x 10^-4) l) ] ^1/2, where l is the length of the camera box (in millimeters). what is the optimum diameter for a pinhole camera if the camera box has a length of 10 centimeters
