Simplify the following expression: (3)(-4) + (3)(4) - 1

-1

To simplify the expression (3)(-4) + (3)(4) - 1, we start by performing the multiplications first.

1. Calculate (3)(-4):

This gives us -12.

2. Next, calculate (3)(4):

This results in 12.

Now we can rewrite the expression incorporating these results:

-12 + 12 - 1.

3. Adding -12 and 12 yields 0:

0 - 1 gives us -1.

Thus, the final result of the expression is indeed -1. This confirms that the correct answer is the option that represents -1.
