the length of a rectangular room is 16 less than four times the width. the perimeter of the room is 68 feet. find the length and the width​

Length = 30.4 ft

Width = 3.6 ft

Step-by-step explanation:

Width: x

Length: 4x + 16

2(x) + 2 (4x + 16) = 68

2x + 8x + 32= 68

10x = 68 - 32

x = 36/10

x = 3.6

Width = 3.6 ft

Length: 30.4 ft

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.
