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

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

If the matrix A=[[8,-6,2],[-6,7,-4],[2,-4,lambda]] is singular then lambda is

Find the rank of A=[[8,1,3,6],[0,3,2,2],[-8,-1,-3,4]]

Find the rank of A=[[8,1,3,6],[0,3,2,2],[8,-1,-3,-4]]

3.Find the rank of the matrix: [[1,2,3,4],[2,4,6,8],[-1,-2,-2,-4]]

Find the rank of the matrix A=[[9,7,3,6],[5,-1,4,1],[6,8,2,4]]

If A=[[2,31,2]] and I=[[1,00,1]], then find lambda,mu so that A^(2)=lambda A+mu I

ABC is a triangle where A=(2,3,5)B=(-1,2,2) and C(lambda,5 mu) if the median through A is equally inclined to the axes then: lambda=mu=5 (b) lambda=5,mu=7lambda=6,mu=9(d)lambda=0,mu=0

If the points (6, -1, 2), (8, -7, lambda) and (5, 2, 4) are collinear then lambda=
