A painter made the table below to show the amount of paint it takes to cover a certain amount of square feet. The amount of paint varies directly with the area of each wall. Amount of Paint and Size of Wall Area of wall feet squared, x 64 144 400 Amount of paint (pints), y 4 9 25 How much paint should the painter expect to use to paint a wall with an area of 256 square feet?

nope.   happens to me as well.

the equation of the parabola is y2=12x

explanation:

the vertex is midway between the focus ad the directrix

so, the vertex is (0,0)

let p=(x,y) be a point on the parabola.

the distance of p from the directrix is equal to the distance from the focus.

x+3=√(x−3)2+(y−0)2

(x+3)2=(x−3)2+y2

x2+6x+9=x2−6x+9+y2

y2=12x

54 is the anser you are looking for

i think the answer is d.
