y^2 = 28x
<em><u>Step-by-step explanation:</u></em>
Since the directrix is horizontal, use the equation of a parabola that opens left or right.
(y−k)^2 = 4p(x−h)
Find the vertex.
(0,0)
Find the distance from the focus to the vertex.
p = 7
Substitute in the known values for the variables into the equation
(y−k)^2 = 4p(x−h).
(y−0)^2 = 4(7)(x−0)
Simplify.
<em>y^2 = 28x</em>
The value of x is 27
Explanation:
5x-50=3x+4
5x-3x=4+50
2x=54
x=27
A circle with a radius of 7cm. I know this is late lol. A square is equilateral so all sides are equal. To find the side lengths given the area you just need to take the square root of the area. You get 14cm. If you put a circle in the square the radius would just be half of one side.
