If the vectors 2a - b + c, a + 2b - 3c, 3a + mb + 5c are linearly dependent, then m =

If three vectors xa-2b+3c, -2a+yb-4c and -zb+3c are coplanar, where a,b and c are unit (or any) vectors then

Show that the vectors a-2b+4c,-2a+3b-6c and -b+2c are coplanar vector, where a,b,c are non-coplanar vectors.

Show that the vectors a-2b+4c,-2a+3b-6c and -b+2c are coplanar vector, where a,b,c are non-coplanar vectors.

Show that the vectors a-2b+4c,-2a+3b-6c and -b+2c are coplanar vector, where a,b,c are non-coplanar vectors.

Show that the vectors a-2b+4c,-2a+3b-6c and -b+2c are coplanar vector, where a,b,c are non-coplanar vectors.

Show that the vectors a-2b+4c,-2a+3b-6c and -b+2c are coplanar vector, where a,b,c are non-coplanar vectors.

Let a, b and c be three non zero vectors, no two of which are collinear. If the vector a + 2b is collinear with c, and b + 3c is collinear with a, then a + 2b + 6c =
