Step-by-step explanation:
Given



Required
The length of the longest segment (d)
This is calculated using:

So, we have:

Using a calculator, the equation becomes

Take square roots

It is called effective interest rate.
For example, you invest in a bond wich pays 5% annual interest rate and it compounds semiannually.
The first semester you win 2.5% over the capital invested and in the second semester you win 2.5% over the capital plus the interested earned in the first semester. Then the effecive interest rate is higher than 5%.

I'm not sure how many equations you are asking for, but hopefully, you can use what I wrote here to solve your actual question. Here is my go:
3x+10+2x+2+5x
First, add all the x's together:
3x+2x+5x=10x
Next, add all our numerals together:
10+2=12
Put it together!
10x+12
