Answer:
Expression = 2 × 7 + 3 + 3
Evaluation of the expression = 20
Step-by-step explanation:
Number of laps Glenn swam every morning = 2
Number of days for which he swam these laps = 7 days
⇒ Number of laps swam in a week = 2 × 7
Number of laps swam with his friend on Tuesday = 3
Number of laps swam with his friend on Thursday = 3
So, Expression that show the number of laps he swam during the week = 2 × 7 + 3 + 3
By evaluating the above expression, the total number of laps he swam that week = 14 + 3 + 3 = 20 laps
