PLEASE HELP IMMEDIATELY The radius of Circle A is 4 cm. The radius of Circle B is 4 cm greater than the radius of
Circle A. The radius of Circle C is 4 cm greater than the radius of Circle B. The radius of Circle D is
3 cm less than the radius of Circle C. What is the area of each circle? How many times greater
than the area of Circle A is the area of Circle D?

Correct answer is Zero.

We can determine this by finding the discriminant of the function.

Discriminant = (-3)²- 4(1)(4) = - 7

Since the discriminant is negative, this means the the zeros of the function are complex and so the graph does not cross x-axis at any point.

Since, the graph is not crossing x-axis at any point, the graph has no real root.
