Hi who wants some free points y'all

sure have a very nice day

Explanation:

thanks bro : )

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the answer would be c. motion and direction

i hope this : )
