Answer: 
Step-by-step explanation:
By definition, the perimeter of a rectangle is:
Where "l" is the lenght and "w" is the width.
If you solve for "l":
In this case, you know that the following expression represents the perimeter of the rectangle:
And the width of that rectanle is represented wih this expression:
Therefore, based on the explained above, you can conclude that the lenght of that rectangle is given by:
Finally, simplifying the expression, you get:
This solution has no solutions because when you do a substitution method you might end up getting rid of the variable and left with a constant.

Find the length of Samson's shadow
The question can be illustrated with the attached figure where Samson's shadow is represented with x.
To solve for x, we make use of the following equivalent ratios:
Convert to fraction
Cross Multiply
Make x the subject
<em>Hence, Samson's shadow is 40ft</em>
D because the negative line goes down and well yeah
