Weegy: I understand that you need assistance but the given polynomials lacks operations in between the numbers. 3x z 9 3x. What operation is in between 3xz^9? 3x z 9-3x- 16y-z 9- 3x-z 9, is this the given? If so, the answer is -2z^9-6x+3z^9x-16y. User: Simplify (2n + 5) - (3n + 7) + (4n - 9).
-3n - 11
3n - 11
-3n + 11
3n + 11 Weegy: The answer is 3n-11 (More)

Weegy: (y^(3)-6y^(2)+5y)-(2y^(2)-3y-5)
Multiply -1 by each term inside the parentheses.
y^(3)-6y^(2)+5y+-2y^(2)+3y+5
Since -6y^(2) and -2y^(2) are like terms, [ subtract 2y^(2) from -6y^(2) to get -8y^(2).
y^(3)-8y^(2)+5y+3y+5
Since 5y and 3y are like terms, add 3y to 5y to get 8y.|||

y^(3)-8y^(2)+8y+5 is the answer. ] User: Score:
Subtract -2k3 + k2 - 9 from 5k3 - 3k + 7.
3k3+ k2- 3k - 2
-7k3+ k2+ 3k - 16
7k3- k2- 3k + 16 Weegy: The answer is 7 k^3+k^2-3 k-2 (More)
