Answer:
The center is:
(2, -4)
Step-by-step explanation:
We have the following equation
The general equation of a circle has the following form
Where r is the radius and the point (h, k) is the center of the circle
To transform the given equation in the general equation of a circumference we must use the method of square completions
Step 1
<u>Step 2</u>
<u> </u>Add and subtract 
For an equation of the form
<u>Step 3 </u> Factor the expressions within the parentheses
<u>Step 4 Simplify</u>
Finally
The center is:
(2, -4)
The answer is D and not b because it’s not 90 it’s 09

Answer:
k = 28
Step-by-step explanation:
12/k = 18/42
Cross multiply.
18k = 12 * 42
18k = 504
Divide both sides by 18.
k = 28
Answer:The answer is 12.8
Step-by-step explanation:
8 and 10 are the side lengths so you would put that check mark thingy and then under it you put 8 squared and 10 squared and then you add it up. If you have the side length and the right length (which is the x) you would subtract because the right length is the longest.
