\( \lim _ { x \rightarrow 0 ^ { - } } \frac { 2 e ^ { 3 x } - 6 \tan ( x ) + 2 x ^ { 2 } - 2 } { 6 \arcsin ( x + x ^ { 3 } ) - 6 x - 6 x ^ { 3 } } \)

Can a tessellation be created using only regular ten-sided polygons? Explain your answer. Choose the correct answer below. A. No, because each angle of a regular ten-sided polygon measures \( 144^{\circ} \) and \( 360^{\circ} \) is not a multiple of \( 144^{\circ} \). B. Yes, because 360 is a multiple of 10 and 10 regular ten-sided polygons can fit into \( 360^{\circ} \). C. No, because the sum of the measures of the angles of a ten-sided polygon is \( 1440^{\circ} \) and \( 1440^{\circ} \) is a multiple of \( 360^{\circ} \). D. Yes, because any regular polygon can create a tessellation.
