Answer:

Step-by-step explanation:
Perimeter of a square:
The perimeter of a square of side x is given by:

Perimeter of a rectangle:
The perimeter of a rectangle of length l and width w is given by:

The length of the sides of a square measure 2x-5.
This means that the perimeter of the square is:

The length of a rectangle measures 2x, and the width measures x + 2.
This means that the perimeter of the rectangle is:

For what value of x is the perimeter of the square the same as the perimeter of the rectangle?
This is x for which:

So





Answer:So, since it is continuously, we need to think of PERT
A=P\times e^{rt}
So, we just plug our numbers in to solve for T
8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t
It will take 15.479 years
