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

  1. -1

  2. 1

  3. 23

  4. 24

The correct answer is: -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.
