A parabola with a vertex at (0, 0) has a directrix that crosses the negative part of the y-axis. Which could be the equation of the parabola?

A. x² = -4y
B. x² = 4y
C. y2 = 4x
D. y2 = -4x

it is a reproduction.

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
