If `A=[(5a,-b),(3,2)]` and A adj `A=A A^(T)`, then `5a+b` is equal to

If A=|{:(,5a,-b),(,3,2):}| and A adj A=A A^(T) , then 5a+b is equal to

If A=[5a-b3 2] and A adj A=AA^T , then 5a+b is equal to: (1) -1 (2) 5 (3) 4 (4) 13

2) If A=[[-1,5],[-3,2]] then adj A=

If A={2,3} B={4,5} then A X B is equal to

Let A={:[(2,3,5),(1,0,2),(3,4,5)]:}andA+B-4I=0 , then B is equal to

5.If A=[[2,-2],[4,3]] then adj A=

If A and B are two non-singular matrices of order 3 such that A A^(T)=2I and A^(-1)=A^(T)-A . Adj. (2B^(-1)) , then det. (B) is equal to

If {:S=[(a,b),(c,d)]:} , then adj S is equal to

If A=[(3,4,3),(2,5,7),(1,2,3)] then |Adj(Adj A)|=

If P(A) =1/2 ,P(B) =3/5 and P (A cap B) = 3/10 then P(B/A) is equal to
