Liam owns some rectangular plots of land. All of the plots are the same length, x, and the width of each plot is 5 yards less than the length. The total number of plots Liam owns is 20 more than the length of a plot. If the total area of all the plots Liam owns is 2,688 square yards, which statements about the length of each plot are true?*The equation x3 − 15x2 − 100x − 2,688 = 0 can be used to find the length of each plot.**The equation x3 + 25x2 + 100x − 2,688 = 0 can be used to find the length of each plot.***The equation x3 + 15x2 − 100x – 2,688 = 0 can be used to find the length of each plot.****The length of each plot is 12 yards.*****The length of each plot is 8 yards.
