Which equation describes a circle with center (4,−7) and radius 9? A.
(x−4)2+(y+7)=9
B.
(x−4)2+(y+7)=81
C.
(x+4)2+(y−7)=81
D.
(x+4)2+(y−7)=9

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
