    Assignment:Find the solution set of inequality (40-30+m-40)(40-m+40) ≥525 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 40 - 30 + m - 40 ) * ( 40 - m + 40 ) ≥525         (1)

---

    From inequality(1)：
         45 ≤ m ≤ 65

---

    The final solution set is :
         45 ≤ m ≤ 65
