Which equation illustrates the identity property of multiplication?
a)(a + bi) × c = (ac + bci)
b)(a + bi) × 0 = 0
c)(a + bi) × (c + di) = (c + di) × (a + bi)
d)(a + bi) × 1 = (a + bi)

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
