-3m - 9c + 8m + 12b
(-3m + 8m) + (-9c + 12b)
5m + (-9c + 12b)
5m - 9c + 12b

Answer 2

Пошаговое объяснение:

-3(m + 3c) + 4(2m + 3b) =

-3m - 9c + 8m + 12b = 12b - 9c + 5m

Answer 3

To simplify the expression -3(m+3c)+4(2m+3b), you can follow the order of operations, which is also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's simplify it step by step:

-3(m+3c) + 4(2m+3b)

First, let's simplify the parentheses inside each term:

-3m - 9c + 8m + 12b

Now, let's combine like terms:

(-3m + 8m) + (-9c + 12b)

This simplifies to:

5m + (-9c + 12b)

The final simplified expression is:

5m - 9c + 12b
