HELP MATRICES:

If a= [-4,-3, 2; 0, -5,-2] (2x3 dimension matrix)
c= [ 7,-1; -2,-7] (2x2 dimension matrix)

then -5AA^t+6c =

Answer 1

I'm assuming A is referring to a? If so, the first thing I would do is take the transpose of matrix a, since you have A^t in your equation. Are you familiar with how to do that?

Answer 2

Yes, i transposed A^t=
