Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
![2(3x-5) + 2(x) = 150](https://tex.z-dn.net/?f=2%283x-5%29%20%2B%202%28x%29%20%3D%20150)
Now we just have to solve!
![6x - 10 + 2x = 150](https://tex.z-dn.net/?f=6x%20-%2010%20%2B%202x%20%3D%20150)
When we combine like terms and add ten to both sides, we are left with
, which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x. ![l = 3(20) -5](https://tex.z-dn.net/?f=l%20%3D%203%2820%29%20-5)
This means the length is 55.

Answer:
When x = 2, y = 6
Step-by-step explanation:
Constant of Proportionality: y = kx
(24) = k(8)
24 = 8k
k = 3
y = kx ===> y = 3x
When x = 2:
y = 3x
y = 3(2)
y = 6
