Answer:
![x = \{41,43,47\}](https://tex.z-dn.net/?f=x%20%3D%20%5C%7B41%2C43%2C47%5C%7D)
Step-by-step explanation:
Given
![x = Prime](https://tex.z-dn.net/?f=x%20%3D%20Prime)
![Range = \{x : 40 \le x \le 50\}](https://tex.z-dn.net/?f=Range%20%3D%20%5C%7Bx%20%3A%2040%20%5Cle%20x%20%5Cle%2050%5C%7D)
Required
Values of x
The given range implies that x is a prime number between 40 and 50 (inclusive)
From 40 to 50, the primes are: 41, 43 and 47
Hence:
![x = \{41,43,47\}](https://tex.z-dn.net/?f=x%20%3D%20%5C%7B41%2C43%2C47%5C%7D)
the answer is 17.5 kilometers
Answer:
w=35, L = 17
Step-by-step explanation:
the perimeter is all sides added together to total 104. so,
2L + 2W= 104
the width is one more than twice it's length, so W = 2L + 1
plug that into first equation.
2L + 2(2L+1)=104
distribute:. 2L + 4L + 2= 104 and continue to solve for L
6L + 2= 104 subtract 2 from both sides.
6L = 102, divide both sides by 6
L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1
W= 2(17)+1
W = 35
