Answer:
![(0.4x + 6y)^2](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%5E2)
Step-by-step explanation:
Given
![4.8xy+36y^2+0.16x^2](https://tex.z-dn.net/?f=4.8xy%2B36y%5E2%2B0.16x%5E2)
Required
Express as a binomial squared
![4.8xy+36y^2+0.16x^2](https://tex.z-dn.net/?f=4.8xy%2B36y%5E2%2B0.16x%5E2)
Rewrite as:
![0.16x^2+4.8xy+36y^2](https://tex.z-dn.net/?f=0.16x%5E2%2B4.8xy%2B36y%5E2)
Expand
![0.16x^2 + 2.4xy + 2.4xy + 36y^2](https://tex.z-dn.net/?f=0.16x%5E2%20%2B%202.4xy%20%2B%202.4xy%20%2B%2036y%5E2)
Factorize:
![0.4x(0.4x + 6y) + 6y(0.4x + 6y)](https://tex.z-dn.net/?f=0.4x%280.4x%20%2B%206y%29%20%2B%206y%280.4x%20%2B%206y%29)
Factor out 0.4x + 6y
![(0.4x + 6y)(0.4x + 6y)](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%280.4x%20%2B%206y%29)
Express as a square:
![(0.4x + 6y)^2](https://tex.z-dn.net/?f=%280.4x%20%2B%206y%29%5E2)
Answer:
The difference in both the guessed values is 5 unit
Step-by-step explanation:
The less error computation is done by dividing the difference between the guessed value and the actual value.
Here in this case
Error in case of Fransisco = 55-50 = 5
Error in case of Kazuko = 60 -55 = 5
Hence, both have guessed incorrect value and their incorrect values is either 5 units less or 5 units higher than the actual value.

x =66
Answer:
The volume of the cylinder is about 1256.6 cubic meters.
Step-by-step explanation:
The volume of a cylinder is given by the formula:
![\displaystyle V=\pi r^2h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cpi%20r%5E2h)
Where <em>r</em> is the radius and <em>h</em> is the height.
Our radius is 10 meters and our height is four meters. Substitute:
![\displaystyle V=\pi(10)^2(4)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cpi%2810%29%5E2%284%29)
Evaluate:
![V=400\pi \text{ m}^3\approx 1256.6\text{ m}^3](https://tex.z-dn.net/?f=V%3D400%5Cpi%20%5Ctext%7B%20m%7D%5E3%5Capprox%201256.6%5Ctext%7B%20m%7D%5E3)
Thus, the volume of the cylinder is about 1256.6 cubic meters.
