3 A 2 B = 3 ( 3 2 5 3 ) 2 ( 7 9 1 9 )
= ( 9 6 15 9 ) ( 14 18 2 18 )
= ( 23 12 13 27 )

Linear transformation, T, such that:
T: M 22
( [ x 11 x 12 x 21 x 22 ] ) = [ x 12 5 x 21 x 22 x 11 2 x 12 + 3 x 21 + 4 x 22 3 x 21 x 11 x 12 + x 21 + 3 x 22 ]
What is the matrix that represents this M 22 -> M 22 transformation?
Is it:
[ 0 1 5 1 1 2 3 4 0 0 3 0 1 1 1 3 ]
If so, how could this be multiplied by a 2x2 matrix to give another 2x2 matrix. (2x2 matrices cannot multiply with 4x4 matrices).

Transformation Matrix of a dot product transformation
Let v be a arbitrary vector in R3 and T(x)=v.x. What is the matrix of the transformation T in terms of the components of v? It seems like trying to figure out the matrix using the equation T(x)=Ax does not work, as the left side is a scalar, and the other side is a matrix. Any idea
