Answer:
Step-by-step explanation:
f(x) = a(x-p)(x-9) is the equation of a vertical parabola.
If a>0, the parabola opens upwards.
If a<0, the parabola opens downwards.
Also, the focal length of the parabola is 1/|4a|.
Perimeter=120
ED=x (length)
FE=4x (breadth)
Perimeter of rectangle= 2(l+b)
Given,
2(x+4x)=120
2x+8x=120
10x=120
x=120÷10
x=12
Therefore, value of x is 12
