Answer 2

Let's simplify the given expressions step by step:

1. 5(a - 2b) - (-5k + 6): Distribute the negative sign within the parentheses: 5(a - 2b) + (5k - 6) Distribute 5: 5a - 10b + 5k - 6

2. 4(-2 + 7): Multiply the constants: 4 * 5 = 20

3. (4a - 5b) * (-9): Multiply each term by -9: -36a + 45b

Now, let's combine all the simplified expressions:

5a - 10b + 5k - 6 + 20 - 36a + 45b

Combine like terms:

(5a - 36a) + (-10b + 45b) + 5k + 20 - 6

Simplify further:

-31a + 35b + 5k + 14

So, the simplified expression is:

-31a + 35b + 5k + 14
