C
Step-by-step explanation:
starts with 4 and is multiplied by 3 every term

Explanation
Step 1
We know that the general equation for a circle is

where
(h,k) is the center of the circel
and r is the radius
then, all we need to do is replace
Let

replace the values

therefore, the answer is

R+s-t-(r-s+t)
=2s-t is the answer
People think this answer would be just =2s but I have verified with an online calculator and the answer that textbooks look for regarding this is 2s-t
You would assume you would go r-r and thats 0 so no r's
you would say s-(-s) makes it plus and theres 2s
and you would say -t -(+t) is -t
that's why the answer is 2s-t
At first I also did t-(+t) and thought it would be no t's but the answer is in fact 2s-t
