Match the pairs of equations that represent concentric circles.
3x2 + 3y2 + 12x β 6y β 21 = 0
5x2 + 5y2 β 10x + 40y β 75 = 0
5x2 + 5y2 β 30x + 20y β 10 = 0
4x2 + 4y2 + 16x β 8y β 308 = 0
x2 + y2 β 12x β 8y β 100 = 0
2x2 + 2y2 β 8x + 12y β 40 = 0
4x2 + 4y2 β 16x + 24y β 28 = 0
3x2 + 3y2 β 18x + 12y β 81 = 0
x2 + y2 β 2x + 8y β 13 = 0
x2 + y2 + 24x + 30y + 17 = 0
