Answer: 40

Step-by-step explanation:

For this problem, you need to know the properties of multiplying negative numbers.

- × - = +                         [negative×negative=positive]

- × + = -                         [negative×positive=negative]

+ × - = -                         [positive×negative=negative]

+ × + = +                       [positive×positive=positive]

Now that we have established the different sign changes, we can multiply -8 and -5. Multiplying -8 and -5 would be the first option. We know that our answer would be positive.

(-8)(-5)=40
