Answer:
The length is 
The width is 
Step-by-step explanation:
we know that
The area of rectangle is equal to

we have

so
-----> equation A
------> equation B
substitute equation B in equation A and solve for L


using a graphing tool------> solve the quadratic equation
The solution is 
see the attached figure
<em>Find the value of W</em>
Answer:
18
3/4 equals to .75 if you multiply .75 with 21 you get 18
Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5
Let
L--------> the length of the rectangle
W-------> the width of the rectangle
we know that
the perimeter of the rectangle is equal to

so
---------> equation 
---------> equation 
Substitute equation
in equation 
therefore
<u>the answer is the option</u>
2w+2⋅(5w)≤96
