Answer:
(x - 2) • (4x + 1)
Step-by-step explanation:
Calculate area of the white region inside circle.
Area of the two white triangles in top left and bottom right:
![2 \cdot \frac{1}{2}(6)(6) = 36 ft^2](https://tex.z-dn.net/?f=2%20%5Ccdot%20%5Cfrac%7B1%7D%7B2%7D%286%29%286%29%20%3D%2036%20ft%5E2)
Area of the two white quarter circles in the bottom left and top right:
![2 \cdot \frac{1}{4}\pi (6)^2 = 18\pi ft^2](https://tex.z-dn.net/?f=2%20%5Ccdot%20%5Cfrac%7B1%7D%7B4%7D%5Cpi%20%286%29%5E2%20%3D%2018%5Cpi%20ft%5E2)
Total area of unshaded white region inside circle:
![(36 + 18\pi)ft^2](https://tex.z-dn.net/?f=%2836%20%2B%2018%5Cpi%29ft%5E2%20)
Area of entire circle including the white and shaded regions
![\pi(6)^2 = 36\pi ft^2](https://tex.z-dn.net/?f=%5Cpi%286%29%5E2%20%3D%2036%5Cpi%20ft%5E2)
Area of shaded region is area of entire circle - area of unshaded white region
![36\pi - (36 + 18\pi) = (18\pi - 36) ft^2](https://tex.z-dn.net/?f=36%5Cpi%20-%20%2836%20%2B%2018%5Cpi%29%20%3D%20%2818%5Cpi%20-%2036%29%20ft%5E2)
It’s B because -3 -2 is -5 and 3i+3i is 6i
