If x + y = 12 and xy = 27, x > y, then the value of (x^3-y^3) is: यदि x + y = 12 है और xy = 27 है, जहाँ x > y, तो (x^3-y^3) का मान क्या होगा ?

The equation of the ellipse whose focus is (1, -1) , directrix is the line x-y-3=0 and eccentricity is 1/2 , is: (A) 7x^2 + 2xy + 7y^2 + 7 = 0 (B) 7x^2 + 2xy+7y^2 + 10x - 10y - 7 = 0 (C) 7x^2 + 2xy + 7y^2 - 10x + 10y + 7 = 0 (D) none of these

If 8x^2+y^2- 12x - 4xy + 9= 0 , then the value of (14x - 5y) is: यदि 8x^2+y^2- 12x - 4xy + 9= 0 है, तो (14x - 5y) का मान ज्ञात करें |

If 40% of x equal 50% of y, then y : x is: यदि x का 40% y के 50% के बराबर है, तो y : x है :
