Answer:
4. x=14.1 mi 6.x=8r3 km
Step-by-step explanation:
<h2>
Hello!</h2>
The answer is:
Center: (-4,-4)
Radius: 2 units.
<h2>
Why?</h2>
To solve the problem, using the given formula of a circle, we need to find its standard equation form which is equal to:

Where:
"h" and "k" are the coordinates of the center of the circle and "r" is its radius.
So, we need to complete the square for both variable "x" and "y".
The given equation is:

So, solving we have:



Now, we have that:

So,
Center: (-4,-4)
Radius: 2 units.
Have a nice day!
Note: I have attached a picture for better understanding.
The answer is B because the inverse of a squared number is the square root.
That would be the one and only 22
