4 (- 5) (- 1)
i need help with this one

20

Step-by-step explanation:

When you multiply an even number of negatives together, the outcome is always a positive number.

In this case, let's first figure out (-5) * (-1). Since there are two negative numbers, we know that the result will be positive. Then: 5 * 1 = 5

Now, we just multiply 5 by 4: 5 * 4 = 20

The answer is 20.

Hope this helps!
