Let
![s=](https://tex.z-dn.net/?f=s%3D)
the length of a side of the sign
We get
![s-2=](https://tex.z-dn.net/?f=s-2%3D)
the length of a side of the poster
Difference between areas is 52
So
![s^{2}-(s-2)^{2}=52](https://tex.z-dn.net/?f=s%5E%7B2%7D-%28s-2%29%5E%7B2%7D%3D52)
⇒
![s^{2}-(s^{2}-4s+4)=52](https://tex.z-dn.net/?f=s%5E%7B2%7D-%28s%5E%7B2%7D-4s%2B4%29%3D52)
⇒
![4s-4=52](https://tex.z-dn.net/?f=4s-4%3D52)
⇒
![4s=56](https://tex.z-dn.net/?f=4s%3D56)
⇒
![s=14](https://tex.z-dn.net/?f=s%3D14)
is the length of a side of the sign
Plug into
![s-2=14-2=12](https://tex.z-dn.net/?f=s-2%3D14-2%3D12)
is the length of a side of the poster
Answer:
The number would be 16.
Step-by-step explanation:
If you have a specific number of apples, and then pluck 3 more, you have 19. So this can be modeled as 19-3, which gives you the original
