(-1, -2)

Step-by-step explanation:

The general equation of a circle is given by :-

(x-h)^2+(y-k)^2=r^2 , where (h,k) is center and r is radius of the circle.

Given : The equation of a circle : (x+1)^2+(y+2)^2=49

$\Rightarrow\ (x-(-1))^2+(y-(-2))^2=7^2$

Comparing to the general equation of circle , we get

(h,k)=(-1, -2)

Hence, the coordinates of the center of the circle = (-1, -2)

She can make 50 group

100^2=50
So she will put 2 cookies in every group

And she can make 100 group if she put one cooky in every group
