So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
The diameter of the whole circle is 2*pi*radius . The arc length is then 80/360*pi*radius*=88*pi
radius=88*180/80
=44*180/40
=22*180/20
=11*180/10
=11*18
=(10+1)*18
=198
The diameter is 2*198=(200-2)=400-4=396
SO BASICALLY THE ANSWER IS 396
12000 x 0.40 = 4800
12000 - 4800 = 7200
7200 acres are being logged

B
3 pairs of pants = one of 3 playing cards
chances of picking jeans = 1/3
chances of picking playing card = 1/3
That would be 106.5 degrees
