Two circles are concentric if they have the same center
which equation represents a circle that is concentric with
the circle shown but has a radius that is twice as large?
0.(x – 4)2 + (-6)2 = 4
(x-4)2 + (-6)2 = 16
o (x – 6)2 + (1 – 4)2 = 16
(x - 6)2 + (y – 4)2 = 4

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
