Answer:
<u>Given circle:</u>
The center is at (4, 0) and the radius is 5 units
<u>Lets find the distance from (7, 2) to the center of the circle:</u>
- <u />

Since d < 5, the point (7, 2) lies <u>inside</u> the circle
Its A. x=4
procedure: 3*equation1 - 2*equation2 ⇒ x=4
2 2/3 = [(2*3)+2]/3 =8/3
(8/3)/5=8/(3*5)=8/15
