The answer should be C if you were to add each point.

Answer:

The correct option is C.

Step-by-step explanation:

The given expression is the sum of two matrices.

[ –6   –2    2] + [–3   2   1]

Both are row matrices of order 1 × 3.

We can add two matrices if and only if order of both matrices is same.

In addition of two matrices, we need to add the corresponding elements of the matrices.

[ –6   –2    2] + [–3   2   1]  =  [ -6-3    -2+2   2+1 ]

[ –6   –2    2] + [–3   2   1]  =  [ -9    0   3 ]

The sum of given matrices is [ -9    0   3 ]. Therefore the correct option is C.
