User: (y 3 - 125) ÷ (y - 5)
User: Given: X = r + 2, Y = 2r - 9, and Z = r 2 + 17r + 30.
Simplify [X · Y - Z] ÷ X.
Weegy: Given: X = r + 2, Y = 2r - 9, and Z = r^2 + 17r + 30. [X ? Y - Z] / X = [(r + 2)(2r - 9) - (r^2 + 17r + 30)]/(r + 2) = (2r^2 - 9r + 4r - 18 - r^2 - 17r - 30)/(r + 2) = (r^2 - 22r - 48)/(r + 2) = (r - 24)(r + 2)/(r + 2) = r - 24

5 + 2{x - 4[3x + 7(2 - x)]}
= 5 + 2{x - 4(3x + 14 - 7x)}
= 5 + 2{x - 4(-4x + 14)}
= 5 + 2{x + 16x - 56}
= 5 + 2{17x - 56}
= 5 + 34x - 112
= 34x - 107
