If `A=[3 5 7 9]` is written as `A=P+Q` , where `P` is symmetric and `Q` is skew-symmetric matrix, then write the matrix `P` .

If A=(3 5 7 9) is written as A = P + Q, where P is a symmetric matrix and Q is skew symmetric matrix, then write the matrix P.

If A=[3579] is written as A=P+Q where as A=P+Q, where P is symmetric and Q is skew-symmetric matrix,then write the matrix P.

If A=([3,57,9]) is written as A=P+Q where P is a symmetric matrix and Q is skew symmetric matrix,then write the matrix P.

If a matrix is both symmetric and skew-symmetric matrix, then

If A=[(2,3),(1,0)]=P+Q , where P is symmetric and Q is skew-symmetric, then find the matrix P.

If [(3,5),(7,9)] is written as A + B, where A is the skew-symmetric matrix and B is the symmetric matrix, then write the matrix A.
