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.
4 is 120 apples
5 is 30 pounds of ice
Answer:
When we have a mean M and a standard deviation S, the values that are within the mean absolute deviation are all the values in the interval:
[M -S, M + S]
In this case, we have:
M = 782
S = 52
Then the interval is:
[782 - 52, 782 + 52]
[730, 834]
Then any number between 730 and 834 are possible answers to this question, for example, we can choose:
789 and 801
It's when we break a number apart. Like as if we take 3,864. And we take each number and put it in a area of the number.
3=Thousands.
8=Hundreds.
6=Tens.
4=Ones.
Fairly simple and easy.
