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
Now we just have to solve!
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.
This means the length is 55.

Hi Bamdeedaowzwbi
Lets find the LCD of both fractions which is 14
now make the denominators (bottom numbers) the same as the LCD (14)
Okay now subtract now that the denominators are the same
join the denominators together
simplify it
Answer: 5/14
*Key word in the question was difference, difference in math definition means subtraction.
