when x = 3,

5x + (-2x^2)

= 5(3) - 2(3^2)

= 15 - 18

= -3

5x + (-2x^2)

= 5(3) - 2(3^2)

= 15 - 18

= -3

Simplify -4(x - 7) + (x + 14). **Weegy:** 18 - 2[x + (x - 5)] 18 - 2[2x - 5] 18 - 4x + 10 = -4x + 28 (More)

-4(x - 7) + (x + 14);

-4x + 28 + x + 14

= -3x + 42

-4x + 28 + x + 14

= -3x + 42
