Answer:

Step-by-step explanation:
Recall that the equation of a circle of radius R centered at
is given by:

For your particular case: R = 6,
= 2, and
= -5, therefore the equation becomes:

No. It's rather simple, down to addition. Ask yourself, what does 6 + 8 equal? 6 + 8 = 14. Now is this an odd number? No, 14 is an even number.
I hope this helps! If not I'm sorry.
Solve x by simplifying both sides of the equation & then isolating the variable x=-4 & the negative comes in from the -12
