What is its center?

((left parenthesis

,,comma

))right parenthesis

What is its radius?

If necessary, round your answer to two decimal places.

Step-by-step explanation:

General form of equation of a circle is expressed as where r is the radius of the circle and (a, b) is the center of the circle.

Given the equation of a circle to be , rewriting the equation to conform to the general equation above we have;

Comparing the equation given to the general equation above, a = 20, b = 0.05 and the radius of the circle will be 9. The center (a, b) will be (20, 0.05).

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
