Final answer:
In the given expression, x represents the score the player earned in the third game of bowling, not the average, another player's score, or the total points.
Step-by-step explanation:
The expression 134 + 110 + x represents a formula to calculate the total score a player earned in three games of bowling. Here, the numbers 134 and 110 are the scores from the first two games. Therefore, x represents the score in the third game. It is not an average, not the points scored by another player, and not the total number of points scored in all the games combined.
