The answers to the questions
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: 70 meters.
Step-by-step explanation:
Observe the figure attached.
The distance between the walls is:
<em />
Both triangles are right triangles. Therefore, you can calculate the distance between the walls as following:
- Calculate the distance AD:
- Calculate the distance AE:
Therefore the distance between the walls is:
Whenever you are graphing an inequality,
< or > means the line is dotted
≤ or ≥ means the line is full and complete
The equation is x ≤ 3 so the answer is either A or B
x ≤ 3 means that x is less than or equal to 3, so the part that is shaded blue is supposed to be 3 and below.
The answer is A
