The length of a rectangular flower bed is 2ft longer than the width. if the area is 6ft, then what are the exact length and width? also find the approximate dimensions of the rectangle.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
