Answer:
(f - g)(x) = -2x^3
Step-by-step explanation:
f(x) = x^1.5 - x
-g(x) = -2x^3 - x^1.5 + x
----------------------------------
(f - g)(x) = -2x^3 (answer)
Answer:
Step-by-step explanation:
8. 4p^2 - 8q^2 + 3r^2 + 3p^2 + 5q^2 - 10r^2
7p^2 - 3q^2 - 7r^2
9. 2x^3 - 4x^2 + 3x + 6x^2 - 12x + 9
2x^3 + 2x^2 - 9x + 9
1 : 3 : 6
longest piece is 2.5 longer than the shortest piece.
let x be the shortest piece.
x + 2.5 is the longest piece
x/10 + 3/10 + (x+2.5)/10 = 1
x + 3 + x + 2.5 / 10 = 1
2x + 5.5 = 10
2x = 10 - 5.5
2x = 4.5
x = 4.5/2
x = 2.25 shortest piece.
x + 2.5 = 2.25 + 2.5 = 4.75 longest piece.
ratio of the 2nd piece to the 3rd piece is 3:6
2nd piece is half of the 3rd piece
4.75 x 1/2 = 2.375
1 : 3 : 6
2.25 : 2.375 : 4.75
Answer:
15
Step-by-step explanation:
3 yards in a ft, so 15 yards in 5 ft.
204 /6 = 34
29 +31 +33 + 35 +37 +39 = 207
4th number = 35
