Show answer & explanation

Correct answer: A

Step-by-Step Solution

  1. Break down the expression: The expression is (0.4 * 0.4) + (0.04 * 0.04) + 0.04.

  2. Calculate the first term: 0.4 * 0.4 = 0.16.

  3. Calculate the second term: 0.04 * 0.04 = 0.0016.

  4. Sum all terms: 0.16 + 0.0016 + 0.04.

    • 0.16 + 0.04 = 0.20

    • 0.20 + 0.0016 = 0.2016.

  5. Determine the approximation: The value 0.2016 is approximately equal to 0.20.
