To find the coordinates of vertex \( D' \) after dilating point \( D(2, -2) \) with respect to the origin by a factor of \( 12 \), you need to multiply both the \( x \) and \( y \) coordinates of point \( D \) by the dilation factor \( 12 \).
Starting with point \( D(2, -2) \):
\[ D' = (2 \times 12, -2 \times 12) \] \[ D' = (24, -24) \]
Therefore, the coordinates of vertex \( D' \) after the dilation would be:
\[ (24, -24) \]
