The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.

Step-by-step explanation:

Let,

x be the number of candles sold by Julio in first week.

According to given statement;

Candles sold in first week = x

He sold twice the number of candles the second week as he did the first week.

Candles sold in second week = 2x

In the third week, Julio sold 4 less than the number he sold the first week.

Candles sold in third week = x-4

Total candles sold = First week + Second week + Third week

Total candles sold = x+2x+(x-4)

The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.
