Answer:
7xy + 4x²
Step-by-step explanation:
5xy + x² + 2xy + 3x²
5xy + 2xy + x² + 3x² [ arranging like terms ]
7xy + 4x²
A circle is evenly divided into six equal triangles.
Firstly , we will identify corner points
we can see in the graph corner points
now, we can find value of P at those points
At (0,0):
![P=-3x+4y](https://tex.z-dn.net/?f=%20P%3D-3x%2B4y%20)
we can plug x=0 , y=0
![P=-3*0+4*0](https://tex.z-dn.net/?f=%20P%3D-3%2A0%2B4%2A0%20)
![P=0](https://tex.z-dn.net/?f=%20P%3D0%20)
At (0,8):
![P=-3x+4y](https://tex.z-dn.net/?f=%20P%3D-3x%2B4y%20)
we can plug x=0 , y=8
![P=-3*0+4*8](https://tex.z-dn.net/?f=%20P%3D-3%2A0%2B4%2A8%20)
![P=32](https://tex.z-dn.net/?f=%20P%3D32%20)
At (6,5):
![P=-3x+4y](https://tex.z-dn.net/?f=%20P%3D-3x%2B4y%20)
we can plug x=6 , y=5
![P=-3*6+4*5](https://tex.z-dn.net/?f=%20P%3D-3%2A6%2B4%2A5%20)
![P=2](https://tex.z-dn.net/?f=%20P%3D2%20)
At (8,0):
![P=-3x+4y](https://tex.z-dn.net/?f=%20P%3D-3x%2B4y%20)
we can plug x=8 , y=0
![P=-3*8+4*0](https://tex.z-dn.net/?f=%20P%3D-3%2A8%2B4%2A0%20)
![P=-24](https://tex.z-dn.net/?f=%20P%3D-24%20)
Maximum value:
