Answer: D) [-9 0 3]
These are two matrices (plural for matrix) we're adding here. The idea is to add up the corresponding elements. Since both are 1x3 matrices, addition is defined.
Row1Column1: -6 + (-3) =
-9
Row1Column2: -2+2 =
0
Row1Column3: 2+1 =
3

Add the numbers in the matrices in order. -6 + -3 = -9; -2 + 2 = 0; 2 + 1 = 3. So our solution matrix will have [-9, 0, 3], choice D from above.
