Which expression is equivalent to (3^2)^-2
???

-81
-12
1/81
1/12

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.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the first one, all those points on the line just make a strait line.

step-by-step explanation:

the shape,the size and the distance
