Final answer:
The expression for the phrase 'add 4 to x, subtract the results from 8 and double' is 8 - 2x. However, the correct answer according to the given choices would be A. 16 - 2x, indicating a potential error in the question or options provided.
Step-by-step explanation:
To solve the question "add 4 to x, subtract the results from 8 and double", we must first add 4 to the variable x. We can represent this as:
x + 4
Next, we subtract this result from 8, which can be represented as:
8 - (x + 4)
Distributing the negative sign within the parentheses gives us:
8 - x - 4
Simplifying, we get:
4 - x
Finally, we double the result. When we multiply the expression by 2, we have:
2(4 - x)
Multiplying each term by 2 gives us:
8 - 2x
Therefore, the correct answer is A. 16 - 2x.
