Well,

We can see that there are 8 10's and 3 1's.  So we can write 8 10's followed by 3 1's and join them with addition symbols.

83 = 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 1 + 1 + 1

The equation below describes a circle. what are the coordinates of the center of the circle?
k0ka [10]
Since, the equation involved is a circle let us clearly write the equation first:
(x+5)^2+(y+2)^2=21^2

From the standard equation of the circle:
(x-h)^2+(y-k)^2=r^2
(h,k)=(x,y)

So from the equation given above, our x would be -5, and our y is equivalent to -2.
So the center of our circle is located at the point (-5,-2)
