8x because everything else is addition or subtractionZ
Answer:
![Length = 98](https://tex.z-dn.net/?f=Length%20%3D%2098)
Step-by-step explanation:
Given
![AO = 5x - 1](https://tex.z-dn.net/?f=AO%20%3D%205x%20-%201)
![BO = 4x + 9](https://tex.z-dn.net/?f=BO%20%3D%204x%20%2B%209)
Required:
The length of the diagonal
Since AO and BO are diagonals that meets at O, we have:
![AO=BO](https://tex.z-dn.net/?f=AO%3DBO)
This gives
![5x - 1 = 4x + 9](https://tex.z-dn.net/?f=5x%20-%201%20%3D%204x%20%2B%209)
Collect Like Terms
![5x - 4x = 1 + 9](https://tex.z-dn.net/?f=5x%20-%204x%20%3D%201%20%2B%209)
![x = 10](https://tex.z-dn.net/?f=x%20%3D%2010)
Subsitute 10 for x in ![AO = 5x - 1](https://tex.z-dn.net/?f=AO%20%3D%205x%20-%201)
![AO = 5 * 10 - 1](https://tex.z-dn.net/?f=AO%20%3D%205%20%2A%2010%20-%201)
![AO = 50 - 1](https://tex.z-dn.net/?f=AO%20%3D%2050%20-%201)
![AO = 49](https://tex.z-dn.net/?f=AO%20%3D%2049)
The length of the diameter is:
![Length = AO * 2](https://tex.z-dn.net/?f=Length%20%3D%20AO%20%2A%202)
![Length = 49 * 2](https://tex.z-dn.net/?f=Length%20%3D%2049%20%2A%202)
![Length = 98](https://tex.z-dn.net/?f=Length%20%3D%2098)
The question is simply asking you to compute the area.
Area = Length * breadth.
Area = 18 inches * 24.5 inches = ------- square inches. Use your calculator.
So that would be your answer in square inches.
