Explanation:

Let's solve the equation step by step to find the correct option:

- Start by solving the square root:

\(\sqrt{2025}\) = 45

- Divide by 9:

45 ÷ 9 = 5

- Multiply by 3:

5 × 3 = 15

- Calculate inside the parentheses:

(15 - 7) = 8

- Multiply by the result of the parentheses:

15 × 8 = 120

- Add 40 to the product:

120 + 40 = 160

- Therefore, the correct option is 160.

- Option Summary:

1. 158

2. 160
