Answer 2

To simplify the expression -4(a - 2c) + (4a - 9c), you need to apply the distributive property and combine like terms. Let's break it down step by step:

-4(a - 2c) + (4a - 9c)

First, let's simplify the expression within the parentheses: -4(a - 2c) = -4a + 8c

Now we can rewrite the expression with the simplified terms: -4a + 8c + (4a - 9c)

Next, let's remove the parentheses and combine like terms: -4a + 4a + 8c - 9c

The 4a and -4a terms cancel each other out: 0a + 8c - 9c

Now, combine the like terms:

• c

Therefore, the simplified expression -4(a - 2c) + (4a - 9c) is equal to -c.
