11. The police department uses a formula to determine the speed at which a car was going when the driver applied the brakes, by measuring the distance of the skid marks. The equation d = 0.0372 +r models the distance, d, in feet traveled after applying the brakes in a car moving 7 miles per hour (r is the speed of the car). Factor the equation. Od=r(0.03r+1) Od 0.03r(r+1) d=r(r+1) Od 0.03r(0.03r+1) This equation is already completely factored.
