Step-by-step explanation:
Sorry about the first time,
so if you follow the order of operations you would do multiplication first so 5*2=10 then following up with addition so add five to get 15.
And if we compare this to the general equation for a circle:
We see that the radius is and the center would be
Step-by-step explanation:
For this case we have the following equation:
We need to complete the square for x and y like this:
And simplifying we got:
