दो समांतर समतलो x+y+z-5=0 तथा 2x+2y+2z+7=0 की बीच की दुरी ज्ञात कीजिये

If x+y+z=19, x^2+y^2+z^2=133 and xz=y^2 , then the difference between z and x is : यदि x^2+y^2+z^2=133 तथा xz=y^2 है, तो z और x के बीच क्या अंतर है ?

Prove that the lines 3x + 2y + z – 5 = 0 = x + y – 2z – 3 and 2x – y – z = 0 = 7x + 10y – 8z – 15 are perpendicular

The lines x + y + z - 3 = 0 = 2x - y + 5z - 6 and x - y - z + 1 = 0 = 2x + 3y + 7z - k are coplanar then k equals

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

The number of solutions of the system of equations x+y+z = 4, 2x + 5y – 2z = 3 and x + 7y – 7z = 5, is /are a)0 b)1 c)2 d)infinite

The planes 2x + 5y + 3z = 0, x-y+4z = 2 and7y-5z + 4 = 0

Solve the system : 2x+3y-z=0, x+y+z=0, 2x+y+2z=0 .

If 7x + 6y - 2z = 0, 3x + 4y + 2z = 0, x - 2y - 6z = 0 then which option is correct

If 7x + 6y - 2z = 0, 3x + 4y + 2z = 0, x - 2y - 6z = 0 then which option is correct
