408 round to the nearest tenth: 410
Answer:
893.3816
Step-by-step explanation:
pretty sure your converting gallons into pounds and if that's the case 4 gallons is 33.3816 lbs so I added 860 + 33.38.16 then I got 893.3816
(3x^2 - 5x +3) + (-2x -3x)
=3x^2-5x+3 + (6x^2)
=9x^2-5x+3
Each side after the cut-out is (s-2c) where s is the original side length and c is the size of the cut so:
V=hlw, h=x and l and w are both (x-8)
V=x(x-8)(x-8)
V=x(x^2-16x+64)
V=x^3-16x^2+64x
