Step-by-step explanation:
Data
140
Process
1.- Find the prime factors of 140, starting with 2, then, 3, 5, 7, etc
140 2
70 2
35 5
7 7
1
2.- Write 140 as a composition of prime factors
140 = (2²)(5)(7)
3.- Conclusion
The prime factors of 140 are 2², 5 and 7
The length (L) of the rectangle can be written as a function of the width (W)
:
Now since we know Area = Width*Length, we can write the area as a function of the width:
Distributing the W inside the parentheses we have:
We know the area is 54 ft^2, so we can rewrite it as:
Now solve for W by factoring (or by applying the quadratic formula):
Factor out a common 2W from the first two terms and a 9 from the last two terms:
Regroup the terms to get our fully factored equation:
This gives us the roots W = 6 and W = -9/2, but width can't be negative so we have width = 6 ft. Then remember that the length L = 2W - 3, so our length is:
So now we know that our rectangle is 9 feet long and 6 feet wide.
Answer:
I believe the ans is (B) 40/9
51.2 because if divide you will get a total if 51.2
