Answer:
x = 4 and the expression when evaluated at x = 4, is 16.
Explanation:
For this problem, we will simply look at the wording of the question and the given expression. The question ask, "What would x be equal to if x equaled 4 in this: 4x?"
In the problem, we are already given that x = 4 in the following expression, so the answer to the question is x = 4. If we were to evaluate the expression when x = 4, we would say the following:
If x = 4, then:
4x
= 4(4)
= 16
Hence, the expression would be 16 if evaluated when x = 4.
Cheers.
