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).
If there are 1.5 times as many pairs of walking shoes as there are running shoes on display, then it is best to take each amount of running shoes and multiply it by 1.5, if doing that equals the amount of walking shoes, then it would be correct. Which in this case, would be D.
Answer: Feet
Step-by-step explanation:
4x - 6 + x + 3.....when x = 8
4(8) - 6 + 8 + 3 =
32 - 6 + 8 + 3 =
43 - 6 =
