What is the center and radius?

x^2+y^2+6x-6y=-14

Therefore,

Step-by-step explanation:

Given:

A Equation of a Circle that is

Which can be written as

To Find:

Center C( -g , -f ) = ?

radius = r =?

Solution:

General Equation of a Circle is given as

On Comparing the Given equation with the General equation we get the following values,

Now, Center and Radius for above circle is given as

Therefore,

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

the answer is b
