The quotient of a number and 6 plus 3 is 11

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Solve each equation using the quadratic formula. find the exact solutions. 6n^2 + 4n - 11

For the inequality |c| < |d| to be true, which of the following must be true?
