Answer 1

Multiply the polynomials (2r−5)(r+4)

(___)r2+(___)r+(___)

Answer 2

To simplify the expression \((a^2 - 11) + (3a^2 - 4a + 6)\), we can combine like terms.

1. Combine the \(a^2\) terms:
- \(a^2 + 3a^2 = 4a^2\)

2. Combine the \(a\) terms:
- There is \(-4a\) from the second part and no \(a\) term from the first part, so it remains \(-4a\).

3. Combine the constant terms:
- \(-11 + 6 = -5\)

Now, putting it all together, we have:
\[
4a^2 - 4a - 5
\]

So, the correct answer is:

**4a² - 4a - 5**
