What is the perimeter of a square with an area of 900 square feet

120 ft.

Step-by-step explanation:

The area of a square is a². The area of this square is 900 ft², so you need to square root it to get the length of one side. √900 is 30, so each side of the square is 30 ft since all sides of a square all equal. To find the perimeter multiply 30×4 to get 120 ft. Hope this helps :)

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.
