Answer:
Δx = 4.5
Step-by-step explanation:
Assuming that x is a varying quantity, the change in the value of x (Δx) is determined by the difference between the final value of x and the initial value of x.
In this case, the final value is 8 and the initial value is 3.5, therefore:
[tex]\Delta x =8-3.5\\\Delta x = 4.5[/tex]
The change in the value of x is 4.5
