Question

In the following exercises, simplify each expression.

$\left(8-11\right)\left(9-12\right)$

Short answer

9

Step-by-step solution

Step 1. Given Information

The given expression is$\left(8-11\right)\left(9-12\right)$.

Step 2. Simplify the expression inside the parentheses.

• Subtract 11 from 8 to solve $\left(8-11\right)$.

$\left(8-11\right)=\left(-3\right)$

• Subtract 12 from 9 to solve $\left(9-12\right)$.

$\left(9-12\right)=\left(-3\right)$

Step 3. Simplify the obtained expression -3-3.

Since the signs are the same for both the obtained numbers in the previous step, the sign of the product of these numbers will be positive.

$\left(-3\right)\left(-3\right)=9$

Step 4. Conclusion

The resultant value is 9.
