X= ![\frac{2}{5} \times \text{time taken to study science}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Ctext%7Btime%20taken%20to%20study%20science%7D)
X=![\frac{2}{5} \times \frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D%20%5Ctimes%20%5Cfrac%7B3%7D%7B8%7D)
X=![\frac{6}{40}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B40%7D)
X=![\frac{3}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B20%7D)
Answer:

We have,
Height of each tin is 5 cm
The area of the lid of the tin is 35 square centimeters.
It is required to find the volume of the cat food that the tin contains. Volume of the box is also given by the product of area and height such that,
![V=A\times h\\\\V=35\times 5\\\\V=175\ cm^3](https://tex.z-dn.net/?f=V%3DA%5Ctimes%20h%5C%5C%5C%5CV%3D35%5Ctimes%205%5C%5C%5C%5CV%3D175%5C%20cm%5E3)

Answer:
n^2+2n+1
Step-by-step explanation:
-2-8-18-32-50
difference=-6-10-14-18
common differences=-4-4-4-4-4
-2-8-18-32-50
n^2=1,4,9,16,25
minus it
=-1,-4,-9,-16,-25
differences 2,5,7,9
common differences=2
2,4,6,8
so 2n+1
so the answer is n^2+2n+1
