Answer
By Th.8, the columns of K are linearly dependent,
and they do not span $\mathbb{R}^{n}$.
Work Step by Step
The statements in Th.8
$\mathrm{b}. \quad A$ is row equivalent to the $n\times n$ identity matrix.
$\mathrm{e}.\quad$ The columns of $A$ form a linearly independent set.
$\mathrm{h}.\ \quad$The columns of $A$ span $\mathbb{R}^{n}$.
are all false when A=K.
Thus,
the columns of K are linearly dependent,
and they do not span $\mathbb{R}^{n}$.
