$- 20 n + 40$

#### Explanation:

The distributive property means to multiply all the numbers inside parenthesis by the number(s) outside of the parenthesis.

So $- 5 \left(4 n - 8\right) = - 5 \times 4 n - 5 \times - 8$

$- 5 \times n = - 20 n$ ( a negative times a positive = a negative)

Think about it this way negative can mean to take away a positive can mean something good so to take away something good is bad. or negative.

$- 5 \times - 8 = + 40$ ( a negative times a negative = a positive)

Think about it this way to take away a something bad is good or positive.

so $- 5 \times 4 n - 5 \times - 8 = - 20 n + 40$
