(-20+17-8+9)*(-14)

To solve the expression \((-20 + 17 - 8 + 9) \times (-14)\), we first simplify the expression inside the parentheses.

1. Calculate \(-20 + 17\): \[ -20 + 17 = -3 \]

2. Now, include the next number: \[ -3 - 8 = -11 \]

3. Finally, add 9: \[ -11 + 9 = -2 \]

Now we have: \[ (-20 + 17 - 8 + 9) = -2 \]

Next, we will multiply this result by \(-14\): \[ -2 \times -14 = 28 \]

Thus, the final result is: \[ \boxed{28} \]
