Hello!
The length and width are given.
We know the formula for calculating perimeter :

Let's solve!
- Perimeter = 2(123 + 17k + 24k - 49)
- Perimeter = 2(41k + 74)

∴ The perimeter is 82k + 148.
I did my math and I think 41 minuets but are u adding or subracting
The mathematical expression for the given statement is 50 + 10x
<h3>How to write a mathematical expression for this statement?</h3>
The given parameters are:
Initial distance = 50 laps
Rate of increment = 10 laps each week
Represent the number of weeks with x
So, we have:
Number of laps = Initial distance + Rate of increment * Number of weeks
This gives
Number of laps = 50 + 10 * x
Evaluate
Number of laps = 50 + 10x
Hence, the mathematical expression for the given statement is 50 + 10x
