Final answer:
The expression can be simplified by combining like terms to get 22x + 5.
Step-by-step explanation:
The expression (-3x - 12) + (17 + 5x) + 2x + (-5) + 8x + (-29) + 8x + 29 + 2x + 5 can be simplified by combining like terms.
First, combine the x terms together: -3x + 5x + 2x + 8x + 8x + 2x = 22x.
Next, combine the constant terms together: -12 + 17 - 5 - 29 + 29 + 5 = 5.
Therefore, the simplified expression is 22x + 5.
