Giving 40 points! solve each given equation and show your work. tell whether it has one solution, an infinite number of solutions, or no solutions, and identify each equation as an identity, a contradiction, or neither. (a) 3x - 5 + x = 2x - 3 + 2 + 2x (b) 4x + 5 - 6x = -x +3 -x +2 (c) 8x + 2 - 6 = 4x +8 +3x

The reflexive property of congruence lets you say that ∠pqr ≅

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
