Solution

Problem 11 :

Solution

Problem 12 :

Solution

1)  (x + 18)2 + (y + 9)2 = 1

2)   x2 + (y + 1)2 = 153

3) (x + 15)2 + (y - 3√7)2  = 2

4) (x + 11)2 + (y + 14)2  = 16

5)  (x + 5)2 + (y - 12)2  = 16

6)  (x - 15)2 + (y - 14)2  = 15

7) (x - 2)2 + (y + 5)2  = 97

8) (x - 14)2 + (y - 17)2  = 1

9) (x + 11)2 + (y + 8)2 = 16

10) (x + 6)2 + (y + 15)2 = 5

11)   x2 + (y - 3)2 = 9

12) (x - 4)2 + (y + 3)2 = 1
