Final answer:
The correct formula for the length x of the plot of land is not provided in the question; additional information is required for an accurate calculation.
Step-by-step explanation:
None of the presented choices, A) x = Murch Road - right-of-way, B) x = right-of-way - Murch Road, C) x = Murch Road + right-of-way, D) x = 2 * (Murch Road - right-of-way), seems to directly correspond to the available scenarios described. If the length of the plot of land, x, along Main Street between Murch Road and the right-of-way is to be calculated, additional information would be needed to provide an accurate calculation. Typically, the length x would be the difference between the position on Main Street corresponding to Murch Road and the position corresponding to the right-of-way, assuming that Murch Road and the right-of-way are two points along Main Street with measureable positions.
