For this case we must find an expression equivalent to:

[tex]-3 (-x + 12)[/tex]

So:

We apply distributive property, which by definition establishes:

[tex]a (b + c) = ab + ac[/tex]

On the other hand:

[tex]- * - = +\\- * + = -[/tex]

[tex]-3 (-x + 12) = 3x-3 * 12 = 3x-36[/tex]

Thus, an expression equivalent to [tex]-3 (-x + 12)\ is\ 3x-36[/tex]

Answer:

[tex]3x-36[/tex]
