Provide an appropriate response.
-If A is a 5 × 2 matrix and A+ K = A, what can you say about K?
A)K is a 2 × 5 matrix and each of its entries is the negative of the corresponding entry of A.
B)K is a 2 × 5 matrix and all entries of K are equal to 0.
C)K is a 5 × 2 matrix and all entries of K are equal to 0.
D)K is a 5 × 2 matrix and each of its entries is the negative of the corresponding entry of A.

Question

Quizplus · Accepted Answer

For the equation A + K = A to hold true, K must be a matrix where all entries are 0, and it must have the same dimensions as A, which are 5 × 2. This ensures that adding K to A leaves A unchanged.
