Let's evaluate each of the given expressions to determine which ones have positive values.
1. Expression: [tex]\(2 \times 8\)[/tex]
Calculation:
[tex]\[
2 \times 8 = 16
\][/tex]
Since 16 is greater than 0, this expression is positive.
2. Expression: [tex]\(-10 \div 12\)[/tex]
Calculation:
[tex]\[
-10 \div 12 \approx -0.8333
\][/tex]
Since [tex]\(-0.8333\)[/tex] is less than 0, this expression is negative.
3. Expression: [tex]\((-2) \times (-2)\)[/tex]
Calculation:
[tex]\[
(-2) \times (-2) = 4
\][/tex]
Since 4 is greater than 0, this expression is positive.
4. Expression: [tex]\(10 \div (-20)\)[/tex]
Calculation:
[tex]\[
10 \div (-20) = -0.5
\][/tex]
Since [tex]\(-0.5\)[/tex] is less than 0, this expression is negative.
5. Expression: [tex]\(6 \times (-8)\)[/tex]
Calculation:
[tex]\[
6 \times (-8) = -48
\][/tex]
Since -48 is less than 0, this expression is negative.
6. Expression: [tex]\(-40 + (-8)\)[/tex]
Calculation:
[tex]\[
-40 + (-8) = -48
\][/tex]
Since -48 is less than 0, this expression is negative.
So, the expressions that result in positive values are:
[tex]\[
2 \times 8 \quad \text{and} \quad (-2) \times (-2)
\][/tex]
Therefore, the expressions that have positive values are [tex]\(2(8)\)[/tex] and [tex]\((-2)(-2)\)[/tex].
