Answer:

240

Explanation:

To evaluate 19^2 - 11^2, we have to use a special product pattern. Since this expression is in the form a^2 - b^2, we use the pattern (a + b)(a - b).


  • (19+11)(19-11)

  • (30)(8)

  • 240

Therefore, the answer is 240.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
