Step-by-step explanation:
256 mm3
cause volume of rectangular prism is l*b*h
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).
Answer:
120
Step-by-step explanation:
To check if x = 9 is the solution, we need to replace every x with 9 and simplify
(3+x)/4 = 3
(3+9)/4 = 3
12/4 = 3
3 = 3
We get the same thing on both sides, so the last equation is a true equation. This means that the first equation is a true equation when x = 9. Therefore, the solution x = 9 is confirmed.
