The path of a soccer ball can be modeled by the equation h(x)=−12x(x−20), where h(x) is the height of the ball, and x is the horizontal distance the ball has traveled. To determine how far the ball has traveled when it hits the ground, Leon set the height equal to 0 and obtained the equation: 0=−12x(x−20). How can he use the Zero Product Property to find the horizontal distance the ball has traveled when the height of the soccer ball equals 0?(1 point)%0D%0AResponses%0D%0A%0D%0APlug in 0 for all the x terms in the function.%0D%0APlug in 0 for all the x terms in the function.%0D%0A%0D%0AHe cannot use the Zero Product Property because the height will never be 0.%0D%0AHe cannot use the Zero Product Property because the height will never be 0.%0D%0A%0D%0ASolve the two equations: −12x=0 and x−20=0.%0D%0ASolve the two equations: negative Start Fraction 1 over 2 End Fraction x equals 0 and x minus 20 equals 0 .%0D%0A%0D%0ACancel out the x and then multiply −12 and −20.%0D%0ACancel out the x and then multiply negative Start Fraction 1 over 2 End Fraction and negative 20 .%0D%0ASkip to navigation%0D%0A%0D%0A%0D%0A%0D%0Apage 18 of 18

The given equation is: 0 = −12x(x − 20)
To use the Zero Product Property, Leon needs to set each factor equal to zero and solve for the variable x:
−12x = 0 and x − 20 = 0
For the first equation, −12x = 0, we can divide by −12 (which doesn't actually change anything since any number times zero is still zero), yielding:
x = 0
For the second equation, x − 20 = 0, we add 20 to each side to isolate x:
x = 20
So, by setting the factors equal to zero and solving for x, Leon finds the two horizontal distances at which the height of the soccer ball is 0: one at the initial position x = 0 where the ball is kicked, and one at x = 20, which is the distance the ball has traveled horizontally when it hits the ground. Hence, the soccer ball has traveled 20 units of horizontal distance when it reaches the ground.
