Since you are not given the following choices, by analyzing this series, it is a geometric progression because their common ratio is constant. Proofing that
4.8/(-3.2) = -1.5, also
-7.2/(4.8) = -1.5, and also
10.8/(-7.2) = -1.5
Answer:
Length: 40 inches
Width: 10 inches
Step-by-step explanation:
Let
width of the rectangle.
From the information "length of a rectangle is four times its width", we can express the length as:
Length = ![4x](https://tex.z-dn.net/?f=4x)
- - - -
Perimeter =
(formula for perimeter of rectangle)
![100=2(4x)+2(x)](https://tex.z-dn.net/?f=100%3D2%284x%29%2B2%28x%29)
![100=8x+2x](https://tex.z-dn.net/?f=100%3D8x%2B2x)
(combine like terms)
inches
∴ The width of the rectangle is 10 inches.
To find the length of the rectangle, we can use substitution:
Length = ![4x](https://tex.z-dn.net/?f=4x)
![=4(10)](https://tex.z-dn.net/?f=%3D4%2810%29)
inches
∴ The length of the rectangle is 40 inches.
Hope this helps :)
