Answer: I don't see that you have a diagram of the swimming pool or any given side measures but assuming it is a rectangle, the algebraic expression would be 2(L+W) where L is the length and W is the width.
Step-by-Step Explanation: So when you are finding the perimeter, you are finding the length of the space surrounding something. So you would add up the length of all its sides to find it. In a rectangle, opposite sides are equal, therefore the length will be equal to the side opposite to it and the width will also be equal to the side opposite to it. So if you were to write the expression like that, you would get L+L+W+W, which can be simplified to 2L+2W, or just 2(L+W).
This can be a perfect square! which 4x4
that is 4^2
That’s some Jesus math there buddy idek
number 5 is not and number 7 is a function because every input has exactly one output
Answer:
The answer is 45 liters = $1890
Step-by-step explanation:
As 1 liter of helium = $42
So multiply 45 liters with $42
Equals $ 1890 for 45 liters of heluim
