The perimeter of a regular pentagon is 41.5cm. write and solve an equation to determine the length of each side of the pentagon.

The length of each side of the pentagon is 8.3 cm

Step-by-step explanation:

we know that

A regular pentagon has five equal sides

The perimeter of a regular pentagon is equal to

where

x is the length side of each side

we have

substitute

Solve for x

Divide by 5 both sides

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
