Answer:

240

Step-by-step 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).

  • [tex](19+11)(19-11)[/tex]
  • [tex](30)(8)[/tex]
  • [tex]240[/tex]

Therefore, the answer is 240.

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