Solve the two equations: negative Start Fraction 1 over 2 End Fraction x equals 0 and x minus 20 equals 0 .

He cannot use the Zero Product Property because the height will never be 0.

Plug in 0 for all the x terms in the function.

To find the horizontal distance the ball has traveled when the height \( h(x) \) equals 0, Leon can use the Zero Product Property, which states that if the product of two factors is zero, then at least one of the factors must be zero.

From the equation:

\[ 0 = -12x(x - 20) \]

he can set each factor equal to zero:

  1. \( -12x = 0 \)
  2. \( x - 20 = 0 \)

Now, solving these equations:

  1. For \( -12x = 0 \): \[ x = 0 \]

  2. For \( x - 20 = 0 \): \[ x = 20 \]

Hence, the ball hits the ground when \( x = 0 \) (the starting point) and \( x = 20 \) (the point where it hits the ground).

So, the correct response is:

Solve the two equations: \( -12x=0 \) and \( x−20=0 \).
