Answer:
see attached
Step-by-step explanation:
You want the value of the matrix expression A^T + 4.2B for the given matrices A and B.
Calculator
The attached calculator display shows the result for what we believe to be the matrix values you have.
As you know, the transpose of a matrix interchanges rows and columns: row 1 becomes column 1, for example. The addition is performed element-by-corresponding element, and the scalar multiplier is applied to each element individually in matrix B before the addition takes place.

Additional comment
We have interpreted 5.9. 0 to mean the second row of matrix B is [5.9, 0], as opposed to [5., 9.0] or something else.
