Let's solve each expression step-by-step:
1. [tex]\(-8 \times (-5)\)[/tex]:
- When multiplying two negative numbers, the result is positive.
- Therefore, [tex]\(-8 \times (-5) = 40\)[/tex].
2. [tex]\(-16 \div 2\)[/tex]:
- Dividing a negative number by a positive number results in a negative number.
- Therefore, [tex]\(-16 \div 2 = -8.0\)[/tex].
So the final results are:
[tex]\[
-8 \times (-5) = 40
\][/tex]
[tex]\[
-16 \div 2 = -8.0
\][/tex]
