Use set builder notation to represent the following set: { -3, -2, -1, 0}

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
