Ineed with a math question, could someone me?

1.) find the length and width of a rectangular sandbox, where the length is 3 feet longer than its width if you are building it with 30 feet of lumber.

The width is 6 feet and the length is 9 feet.

Step-by-step explanation:

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.

1,8,15,22,29,36,43,50
