To determine which expressions are equivalent to $$ 25 + 20 - 2 - (-18) $$, let's simplify the original expression first:

$$
25 + 20 - 2 - (-18) = 25 + 20 - 2 + 18 = 61
$$

Now, let's evaluate each option:

**A. $$ 25 + 20 + (-2) + 18 $$**
$$
25 + 20 + (-2) + 18 = 25 + 20 - 2 + 18 = 61 \quad \text{(Equivalent)}
$$

**B. $$ 20 + 18 + 25 + (-2) $$**
$$
20 + 18 + 25 + (-2) = 20 + 18 + 25 - 2 = 61 \quad \text{(Equivalent)}
$$

**C. $$ 25 + 20 + (-2) + (-18) $$**
$$
25 + 20 + (-2) + (-18) = 25 + 20 - 2 - 18 = 25 \quad \text{(Not Equivalent)}
$$

**D. $$ 20 + (-18) + 25 + (-2) $$**
$$
20 + (-18) + 25 + (-2) = 20 - 18 + 25 - 2 = 25 \quad \text{(Not Equivalent)}
$$

Therefore, the equivalent expressions are **A** and **B**.

**Answer:**  
Options A and B are equivalent to $$ 25+20-2-(-18) $$.
Options A and B are equivalent to $$ 25+20-2-(-18) $$.
