Hello!
When finding the perimeter of a rectangle, you have to consider the properties of a rectangle. A rectangle has two pairs of equal sides where one is the width, while the other one is the length.
Now looking back at your question, it says "... a rectangle that is x units wide" ⇒ you let the width = x ; this is the same with "y units long" ⇒ length = y. Perimeter can just be : P = 24.
Therefore,
The equation would be:
x + x + y + y = P.
2x + 2y = P.
(Sub in P = 24)
∴ 2x + 2y = 24. (This should be your answer.)

Answer:
3v-v² = v(3-v)
Step-by-step explanation:
Use distributive property on the right side of the equality.
Answer:
B. The range of the function is all real numbers
Answer:
1.01 minutes
Step-by-step explanation:
The length of the roll is given to be 304 ft, and Bob's velocity is 5ft/s.
Velocity is defined as the rate of change of displacement over time t:
![v=d/t\\](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C)
The function can be expressed to make t the subject to calculate time taken by Bob;
![v=d/t\\\therefore t=d/v, d=304, v=5\\\\t=\frac{304}{5}\times \frac{1}{60}\ min\\\\t=1.01 \ min](https://tex.z-dn.net/?f=v%3Dd%2Ft%5C%5C%5Ctherefore%20t%3Dd%2Fv%2C%20d%3D304%2C%20v%3D5%5C%5C%5C%5Ct%3D%5Cfrac%7B304%7D%7B5%7D%5Ctimes%20%5Cfrac%7B1%7D%7B60%7D%5C%20min%5C%5C%5C%5Ct%3D1.01%20%5C%20min)
Hence, it takes Bob 1.01 minutes to walk the length of the roll.
Answer: Is the last one. D
Hope this helps
