a.) A = P+P*r*t for r Does anyone else get r = (A/P-1)/t ? b.) d = (sqrt(4*R^2-C^2))/2 for C Does anyone else get C = sqrt((-2d)^2)/4)+R^2 c.) 1/f = 1/q+1/p for q Does anyone else just get f^-1-p^-1=q^-1?

Less complex: b) You lost me on this one. c) I don't see where you solved for q in your attempt. Multiply through by the LCD of fqp
