Answer:
557.8
Step-by-step explanation:
Because the semi circle on the top and the semi circle on the bottom form a circle with an area of 314.16.
The semicirlces on either side form a circle with an area of 66.48.
Then the rectangle in the middle has an area of 9 times 20 which is 180.
If you add those areas together you get the total area which is about 557.8
I hope this is helpful :)

Step by step explanation not needed
3x^2−8x−3
(3x+1)(x−3)
=(3x+1)(x+−3)
=(3x)(x)+(3x)(−3)+(1)(x)+(1)(−3)
=3x^2−9x+x−3
=3x^2−8x−3
P = 499.2 Watt
