Question

(x+2)² + ( y-8)²= (x+3)² + ( y+5)² విలువ ఎంత

Answer 1

Step-by-step explanation:

(x+2)² + (y-8)² = (x+3)² + (y+5)²

x² + 4x + 4 + y² - 16y + 64 = x² + 6x + 9 + y² + 10y + 25

x² + 4x + 4 + y² - 16y + 64 - x² - 6x - 9 - y² - 10y - 25 = 0

- 2x + 38 - 26y = 0

2x + 26y = 38

2 (x + 13y) = 38

x + 13y = 38/2

x + 13y = 19
