Answer:
2x+8
Step-by-step explanation:
So when they say a number, they mean a unknown value.
We can use a variable as this unknown value. In this situration we can call it x.
This phase says "twice a number" or "twice x". This can be though of as 2x.
next it says this number is increased by 8. When they say increased they meanm added to.
So 8 is added to 2x. Or 2x + 8
So its the second answer, 2x+8.
Hope this helps!
