○ Option 1 is the appropriate row echelon form.
○ Option 2 is the appropriate row echelon form.
○ Option 3 is the appropriate row echelon form.
○ Option 4 is the appropriate row echelon form.
○ Option 5 is the appropriate row echelon form.
Let matrix A have order (dimension) 2x4 and let matrix B have order (dimension) 4x4.
What results when you compute A+B?
The resulting matrix will have dimensions of 2x4.
○ The resulting matrix will be a single number (scalar).
The resulting matrix will have dimensions of 4x4.
A+B is undefined since matrix A and B do not have the same dimensions.
