Answer:
![- 18.4](https://tex.z-dn.net/?f=%20-%2018.4)
Step-by-step explanation:
The given expresion is
![- 9.2(4 - x)](https://tex.z-dn.net/?f=%20-%209.2%284%20-%20x%29)
We want to evaluate this expression for x=2.
We substitute x=2 into the expression.
This means that, we will put 2 wherever we see x in the given expresion.
This will give us:
![- 9.2(4 - 2)](https://tex.z-dn.net/?f=%20-%209.2%284%20-%202%29)
Simplify the parenthesis
![- 9.2(2)](https://tex.z-dn.net/?f=%20-%209.2%282%29)
![= - 18.4](https://tex.z-dn.net/?f=%20%3D%20%20-%2018.4)
