No, the correct answer is 23.75. Try plugging it into a calculator.
Answer:
9996
Step-by-step explanation:
Because a square has 4 sides, you would multiply the 8 meters by 4. That would mean that the entire room is 32 squared meters. Then multiply the 32 meters by the cost ($35.00). The total cost of the new carpet is $1,120
Let L = length & W= width
Just rewrite the problem in math:
L=5+2W & Area = L x W=403cm²===> (5+2W).(W)=403.
==>2W²+5W-403 =0 Solve the quadratic equation. & you will get W=13
Plug it to find L =31
There is only one rate of change for f(x) which is 6 unless you have more specifications for the problem.
