+140 Simplify \((2n-2)(n+3) + (n+2)(n-6)\).
The equation \(y = -6t^2 - 10t + 56\) describes the height (in feet) of a ball thrown downward at 10 feet per second from a height of 56 feet from the surface from Mars. In how many seconds will the ball hit the ground? Express your answer as a decimal rounded to the nearest hundredth.
+36916 IF your equation is correct just put 0 in for height ('y') and solve the equation for 't' (likely via the quadratic formula throw out any negative 't' values found)
