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! ♡
