Final answer:

To find the value of the expression 25(-5)25-5, each operation is performed in the order of operations. The final result is -3130, which is not among the multiple-choice options, indicating the correct answer is 'None of the above'.

Step-by-step explanation:

The value of the expression 25(-5)25-5 needs to be evaluated following the order of operations, which is parenthetical expressions, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

  1. First, calculate the parenthetical expression: (-5). Since there is no operation inside the parentheses, this expression remains -5.
  2. Next, perform the multiplication: 25 * -5 which equals -125.
  3. Then, continue with the next multiplication: -125 * 25 which equals -3125.
  4. Lastly, subtract 5: -3125 - 5 which equals -3130.

There is no option that matches -3130 in the provided choices. So the correct answer is None of the above.
