O A. (x-4)2 + (y - 2)2 = 17
O B. (x + 4)2 + (y + 2)2 = 5
OC. (x – 4)2 + (y - 2)2 = 17
OD. (x + 4)2 + (y + 2)2 = 17

White shapes and black shapes are used in a game. some of the shapes are circles. while the rest are squares. the ratio of the number of white shapes to the number of black shapes is 5: 11. the ratio of the number of white cicrles to the number of white squares is 3: 7. the ratio of the number of black circles to the number of black squres is 3: 8. work out what fraction of all the shapes are circles.
