x²+y²-2x-6y-5=0
x²-2x+y²-6y=5
x²-2x+1+y²-6y+9=5+1+9
(x-1)²+(y-3)²=15
(x-1)²+(y-3)²=(V15)²
-> centre of the circle: C(-1,-3)
-> radius of the circle: V15
7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
2x = 8 ... therefore x = 4
4^2 = 16
No, all parallelograms are not squares because squares have to have all 90 degree angles, while parallelograms don't
