Final answer:
The expression 20x - 2x gives a larger value when x=3, resulting in a value of 54.
Step-by-step explanation:
To evaluate 20x - 2x when x=2 and when x=3, we follow these steps:
- First, plug x=2 into the expression: 20(2) - 2(2) = 40 - 4 = 36.
- Then, plug x=3 into the expression: 20(3) - 2(3) = 60 - 6 = 54.
We can see that the expression gives a larger value when x=3, and the value is 54.
