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.
