Chris Built a rectangular snow fort with a perimeter of 24 feet. The length of the fort was 8 feet less than 3 times the width. What was the length (x) and width (y) of the fort
Answers
The length of a rectangular snow fort is 7 feet and the width of a rectangular snow fort is 5 feet.
Given that, Chris Built a rectangular snow fort with a perimeter of 24 feet.
What is the perimeter of a rectangle?
The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Let x be the length of a rectangular snow fort and y be the width of a rectangular snow fort.
The length of the fort was 8 feet less than 3 times the width.
y=3x-8
Now, 2(y+x)=24
⇒ 3x-8+x=12
⇒ 4x=20
⇒ x=5
So, y=3x-8=7
Therefore, the length of a rectangular snow fort is 7 feet and the width of a rectangular snow fort is 5 feet.

24 = 6W + 2W -16
32 = 8W
W = 4.
L = 3W-8
L = 3 (4) -8
L = 12-8
L = 4

Fourth, divide both sides by 3. / Your problem should look like:
Fifth, simplify the fraction to 3. / Your problem should look like:
Sixth, switch your sides. / Your problem should look like:
Answer: c = -3
−14=−5+3c
−14=3c−5
Flip the equation.
3c−5=−14
Add 5 to both sides.
3c−5+5=−14+5
3c=−9
Divide both sides by 3.
3c/3=−9/3

Answer:
A. The value of n can be any positive integer resulting in the same factor
Step-by-step explanation:
Given
--- the right expression
Required
Possible values of n
Expand
Factorize
Factor out
From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible
The above also shows that n can take any positive value.
Hence: (a) is correct
