If `lambda` and `mu` are the co factors of `3` and `-2` respectively in the determinant `|[1,0,-2] , [3,-1,2] , [4,5,6]|` then the value of `lambda+mu=`

If lambda and mu are the cofactors of 3 and -2 respectively in the determinant |{:(1,0,-2),(3,-1,2),(4,5,6):}| the value of lambda+mu is

If lambda "and" mu are the cofactors of 3 and -2 respectively in the determinant |{:(1,0,-2),(3,-1,2),(4,5,6):}| the value of lambda+mu is

If lambda "and" mu are the cofactors of 3 and -2 respectively in the determinant |{:(1,0,-2),(3,-1,2),(4,5,6):}| the value of lambda+mu is

If lambda "and" mu are the cofactors of 3 and -2 respectively in the determinant |{:(1,0,-2),(3,-1,2),(4,5,6):}| the value of lambda+mu is

if ._(1)mu_2 is 1.5, then find the value of lambda_1/lambda_2.

if mu_21 is 1.5, then find the value of lambda_1/lambda_2.

The point (lambda,mu,k) is the foot of the perpendicular from a point (2,4,3) on the line joining the points (1,2,4) and (3,4,5) .then the value of 9 lambda-24 is

A(2,3,5),B(-1,3,2),C( lambda ,5, mu ) are the vertices of a triangle.If the median through A is equally inclined to co-ordinate axes then the value of 3 lambda-2 mu is

If the points (0,1,-2),(3,lambda,-1) and (mu,-3,4) are collinear,then the value of lambda and mu are given by

If the rank of A=[[1,2,3,4],[2,4,6,8],[3,6 ,lambda, mu]] is 1 then lambda+mu
