The perimeter of a 5-sided figure is 45.56 meters. two of the sides have the same length. the sum of the other three side lengths is 24.2 meters. how long is each of the same-length sides? explain i'm horrible at math!

You just purchased two coins at a price of $670 each. because one of the coins is more collectible, you believe that its value will increase at a rate of 7.1 percent per year, while you believe the second coin will only increase at 6.5 percent per year. if you are correct, how much more will the first coin be worth in 15 years?
