Answer 2

To simplify the expression -3(a + 12) - 5(-22a + 6), you can use the distributive property (also known as the distributive law or the distributive property of multiplication over addition). Here's how you do it step by step:

1. Distribute the -3 to both terms inside the first parentheses: -3(a) - 3(12)

2. Distribute the -5 to both terms inside the second parentheses: -5(-22a) - 5(6)

Now, simplify each term:

1. -3(a) = -3a
2. -3(12) = -36
3. -5(-22a) = 110a (because a negative multiplied by a negative is positive)
4. -5(6) = -30

Now, put it all together:

-3(a + 12) - 5(-22a + 6) = -3a - (-36) - 5(110a - 30)

Since we have a double negative (-(-36) is the same as +36), we can simplify further:

-3a + 36 - 5(110a - 30)

Now, let's distribute the -5 inside the second set of parentheses:

-3a + 36 - (5 * 110a) - (5 * -30)

-3a + 36 - 550a + 150

Now, combine like terms:

-3a - 550a = -553a 36 + 150 = 186

So, the simplified expression is:

-553a + 186
