Answer:
16.8
Step-by-step explanation:
3x+2y
3(4)+2(2.4)
12+4.8
16.8
Let's see if that's really true! :)
170=x(17)
170=17x
17x=170
17x / 17=170 / 17
x=10
So the answer to your question is false.
170 is actually 10/1 OR 10 of 17.
Given:
Width of the rectangular yard = x feet
Length of the rectangular yard = x+4 feet
Perimeter of the rectangular yard is:
![P=4x+8](https://tex.z-dn.net/?f=P%3D4x%2B8)
Perimeter of the yard = 84 feet
To find:
The length of the rectangular yard.
Solution:
Perimeter of the yard is 84 feet.
![4x+8=84](https://tex.z-dn.net/?f=4x%2B8%3D84)
![4x=84-8](https://tex.z-dn.net/?f=4x%3D84-8)
![4x=76](https://tex.z-dn.net/?f=4x%3D76)
Divide both sides by 4.
![x=\dfrac{76}{4}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B76%7D%7B4%7D)
![x=19](https://tex.z-dn.net/?f=x%3D19)
So, the width of the rectangular yard is 19 feet.
Length = ![19+4](https://tex.z-dn.net/?f=19%2B4)
Length = ![23](https://tex.z-dn.net/?f=23)
The length of the rectangular field is 23 feet.
Therefore, the correct option is B.
