If `veca,vecb,vecc` are non zero and non coplanar vectors show that the following vector are coplanar: `2veca-3vecb+4vecc, -veca+3vecb-5vecc,-veca+2vecb-3vecc`

If veca,vecb,vecc are non zero and non coplanar vectors show that the following vector are coplanar: 4veca+5vecb+vecc, -vecb-vecc, 5veca+9vecb+4vecc

If veca,vecb,vecc are non zero and non coplanar vectors show that the following vector are coplanar: 5veca+6vecb+7vecc,7veca-8vecb+9vecc, 3veca+20vecb+5vecc

If veca, vecb, vecc are non-coplanar vectors, prove that the following vectors are coplanar. (i) 3veca - 7vecb - 4vecc, 3veca - 2vecb + vecc, veca + vecb + 2vecc (ii) 5veca +6vecb + 7vecc, 7veca - 8vecb + 9vecc, 3veca + 20 vecb + 5vecc

If veca, vecb, vecc , be three on zero non coplanar vectors estabish a linear relation between the vectors: 8vecb+6vecc, veca+vecb+vecc, 2veca-vecb+vecc, veca-vecb-vecc

If veca, vecb, vecc , be three on zero non coplanar vectors estabish a linear relation between the vectors: 4veca+5vecb+vecc,-vecb-vecc, 3veca+9vecb+4vecc,-4veca+4vecb+4vecc

If veca, vecb and vecc are non-coplanar vectors, prove that the four points 2veca+3vecb-vecc, veca-2vecb+3vecc, 3veca+4vecb-2vecc and veca-6vecb+ 6 vecc are coplanar.

If veca, vecb and vecc are three non-zero, non-coplanar vectors,then find the linear relation between the following four vectors : veca-2vecb+3vecc, 2veca-3vecb+4vecc, 3veca-4vecb+ 5vecc, 7veca-11vecb+15vecc .

If veca, vecb and vecc are three non - zero and non - coplanar vectors such that [(veca,vecb,vecc)]=4 , then the value of (veca+3vecb-vecc).((veca-vecb)xx(veca-2vecb-3vecc)) equal to
