User: Simplify (2n + 5) - (3n + 7) + (4n - 9).

Weegy: (2n + 5) - (3n + 7) + (4n - 9)
= 2n + 5 - 3n - 7 + 4n - 9
= (2n - 3n + 4n) + (5 - 7 - 9)
= 3n + - 11

User: Subtract -2k^3 + k^2 - 9 from 5k^3 - 3k + 7.

Weegy: 5k^3 - 3k + 7 - (-2k^3 + k^2 - 9) = 7k^3 - k^2 - 3k + 16

User: Find the sum of 5m + 3n + p, -5p + 3n, and 2n - m.

Weegy: (5m + 3n + p) + (-5p + 3n) + (2n - m) = 4m + 8n - 4p

User: Find the sum of 2x^2 + 3x - 4, 8 - 3x, and -5x 2 + 2.

Weegy: 2x^2 + 3x - 4 + 8 - 3x + (-5x^2 + 2)

= -4 + 8 + 2 + 3x - 3x + 2x^2 - 5x^2;

= -3x^2 + 6

User: Using the polynomials Q = 3x 2 + 5x - 2, R = 2 - x 2, and S = 2x + 5, perform the indicated operation. Q - [R + S]

Weegy: Q = 3x^2 + 5x - 2, R = 2 - x^2, and S = 2x + 5
Q - [R + S]
= (3x^2 + 5x - 2) - [(2 - x^2) + (2x + 5)]
= (3x^2 + 5x - 2) - (2 - x^2 + 2x + 5)
= (3x^2 + 5x - 2) - (7 - x^2 + 2x)
= 3x^2 + 5x - 2 - 7 + x^2 - 2x
= 4x^2 + 3x - 9

User: Simplify -3p 3 + 5p + (-2p 2) + (-4) - 12p + 5 - (-8p 3). Select the answer in descending powers of p.

Weegy: -3p^3 + 5p + (-2p^2) + (-4) - 12p + 5 - (-8p^3)
= -3p^3 + 5p - 2p^2 - 4 - 12p + 5 + 8p^3
= (-3p^3 + 8p^3) - 2p^2 + (5p - 12p) + (-4 + 5)
= 5p^3 - 2p^2 - 7p + 1

User: Simplify a - {b - [c - (d - e) - f] - g}.

Weegy: a - {b - [c - (d - e) - f] - g}
= a - [b - (c - d + e - f) - g]
= a - (b - c + d - e + f - g)
= a - b + c - d + e - f + g
