Step by step solution

Step 1. Given Information

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

Step 2. Simplify the expression inside the parentheses.

Subtract 11 from 8 to solve $(8 - 11)$ .

$(8 - 11) = (- 3)$

Subtract 12 from 9 to solve $(9 - 12)$ .

$(9 - 12) = (- 3)$

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.

$(- 3) (- 3) = 9$

Step 4. Conclusion

The resultant value is 9.
