Help meee plz plz me now

Enter the number of complex zeros for the polynomial function in the box. f(x) = x+ + 5x² +6

Amodel rocket is launched from a roof into a large field. the path of the rocket can be modeled by the equation y = -0.04x^2 + 8.6x + 4.8, where x is the horizontal distance, in meters, from the starting point on the roof and y is the height, in meters, of the rocket above the ground. how far horizontally from its starting point will the rocket land? a. 0.56 m b. 215.56 m c. 431.11 m d. 215.74 m

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
