What is the value of ((x - y)^3 + (y - z)^3 + (z - x)^3)/(9(x - y)(y - z)(z - x)) ?

x y : y z : z x = 1 : 5 : 9 Find ( x + y ) : ( y + z ) : ( z + x ) = ?

The value of ((x-y)^(3)+(y-z)^(3)+(z-x)^(3))/(9(x-y)(y-z)(z-x)) is equal to (a)0(b)(1)/(9)(c)(1)/(3)(d)1

Find the S.D. between the lines : (i) (x)/(2) = (y)/(-3) = (z)/(1) and (x -2)/(3) = (y - 1)/(-5) = (z + 4)/(2) (ii) (x -1)/(2) = (y - 2)/(3) = (z - 3)/(2) and (x + 1)/(3) = (y - 1)/(2) = (z - 1)/(5) (iii) (x + 1)/(7) = (y + 1)/(-6) = (z + 1)/(1) and (x -3)/(1) = (y -5)/(-2) = (z - 7)/(1) (iv) (x - 3)/(3) = (y - 8)/(-1) = (z-3)/(1) and (x + 3)/(-3) = (y +7)/(2) = (z -6)/(4) .

2x-3z + w = 1x-y + 2w = 1-3y + z + w = 1x + y + z = 1

Solve the following set of equations 2x+3y -z = 9; x +y +z = 9; 3x - y - z = -1 .

If x : y : z = 3 : 4 : 9, then what will be the value of (2x + 3y + z) : (2z + x – 3y)?
