Another one lol! Thank you!

Using the quadratic formula find the zeros of the given polynomial -5x^2+3x-11

Aportion of a hiking trail slopes downward at about an 84° angle. to the nearest tenth of a flot, what is the value of x, the distance the hiker traveled along the path, if he has traveled a horizontal distance of 120 feet? a. 143.3 b. 12.5 c. 120.7 d. 130.2

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
