If the origin and the points P(2,3,4), Q(1,2,3) and R(x,y,z) are coplanar, then

If the origin and the point P(2,3,4),Q(,1,2,3)R (x,y,z) are coplanar then: a) x-2y-z=0 b) x+2y+z=0 c) x-2y+z=0 d) 2x-2y+z=0

If the origin and the point p(2,3,4),q(,1,2,3)R (x,y,z) are coplanar then

If the origin and the points A(1, 2, -2), B(1, -2, 3), C(x, y, z) are coplanar, then

If the origin O and the points A ( 1, 2, 3), B (2, 3, 4) and P(x,y,z) are coplaner, then

If the points A(3-x, 3, 3), B(3, 3-y, 3), C(3, 3, 3-z) and D(2, 2, 2) are coplanar, then (1)/(x)+(1)/(y)+(1)/(z) is equal to

If a point R ( 4, y, z ) lies on the line segment joining the points P ( 2, - 3, 4 ) and Q ( 8, 0, 10) then the distance of R from the origin is:

If the image of the point P(1,-2,3) in the plane, 2x+3y-4z+22=0 mesured parallel to the line, (x)/(1)=(y)/(4)=(z)/(5) is Q , then PQ is equal to

If the image of the point P(1,-2,3) in the plane, 2x+3y-4z+22=0 mesured parallel to the line, (x)/(1)=(y)/(4)=(z)/(5) is Q, then PQ is equal to
