<u>Center and Radius</u>
3x² + 3y² + 30x - 42y - 141 = 0
x² + y² + 10x - 14y - 47 = 0
x² + 10x + y² - 14y - 47 = 0
x² + 10x + 25 + y² - 14y - 49 = 0
x² + 10x + 25 + y² - 14y - 49 = 47
x² + 10x + 25 + y² - 14y + 49 = 47 + 25 + 49
x² + 10x + 25 + y² - 14y + 49 = 121
(x + 5)² + (y - 7)² = 121
center: (-5, 7)
radius: 11

What is the value of X? Enter your answer in the box ASAP
Komok [63]
Hello!

The line on the two lines means they equal each other

5x + 10 = 40

Subtract 10 from each side

5x = 30

Divide both sides by 5

x = 6

The answer is 6

Hope this helps!
