If `A=[[2,0,3],[-9,3,-1],[0,2,-3]]`, then `3A-2A^T=?`

If A=[[2,-1,2],[1,3,-4]],B=[[1,-2],[-3,0],[5,4]] then verify that (AB)^(T)=B^(T)A^(T)

If A=[(0,-1,2),(1,0,3),(-2,-3,0)], then A+2A^t equals (A) a (B) -A^t (C) A^t (D) 2A^2

If A=([1,2,1],[0,1,-1],[3,-1,1]) then A^(3)-3A^(2)-A-9=

If A[(2,0,3),(1,-1,2),(3,-2,0)] , then (adj A)A=

If A=[[1, -1, 2], [3, 0, -2], [1, 0, 3]] , then (adjA)A=

If A=[[1,2,3]], B=[(-5,4,0),(0,2,-1),(1,-3,2)] then (A) AB=[(-2),(-1),(4)] (B) AB=[-2,-1,4] (C) AB=[4,-1,2] (D) AB=[(-5,4,0),(0,4,-2),(3,-9,6)]

[[2x,3]][[1,2-3,0]][[x3]]=0

Use product [[1,-1, 2],[ 0, 2,-3],[ 3,-2, 4]] [[-2, 0, 1],[ 9, 2,-3],[ 6, 1,-2]] to solve the system of equation: x-y+2z=1; 2y-3z=1; 3x-2y+4z=2
