Which equation represents a circle with a center at (-3, -5) and a radius of 6 units?
(x - 3)2 + (y – 5)2 = 6
(x - 3)2 + (y – 5)2 = 36
(x + 3)2 + (y + 5)2 = 6
(x + 3)2 + y + 5)2 = 36

the value in side the bracket of completed square term of x is the negative value of the x coordinate of the centre and the same goes with the y term. i.e the correct answer is the fourth.

remember to express (x+3)×(x+3). as(x+3)^2

c. (x + 3)2 + (y + 5)2 = 36

Step-by-step explanation:

on edge

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.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
