Let
x---------> the length of the rectangle
y--------> the width of the rectangle
we know that
A=84 ft²
[area of rectangle]=x*y-----> 84=x*y-----> equation 1
x=y-5------> equation 2
substitute 2 in 1
84=[y-5]*y-----> 84=y²-5y---------> y²-5y-84=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solution is
y=12
x=y-5-----> x=12-5-----> x=7
the answer is
the length of the rectangle is 7 ft
the width of the rectangle is 12 ft
x---------> the length of the rectangle

Answer:
a) The profit will be:
b) Since the profit is -9500 (negative) so, company will not gain any profit if they produce 300 bicycles.
Step-by-step explanation:
Cost of Bicycles=
Revenue generated =
Find a polynomial that represent profits
The formula used for finding profit is:
So, the profit will be:
If the company can produce bicycles y= 300
The profit will be:
Since the profit is -9500 (negative) so, company will not gain any profit if they produce 300 bicycles.
