Answer: the expression that represents the total number of items that have been collected is

7d + 12

Step-by-step explanation:

You are collecting pairs of socks and toothbrushes for a local charity.

Total number of pairs of socks that you would have collected after d days is (4d+5)

Total number of toothbrushes that you would have collected after d days is (3d+7). Therefore, the expression that represents the total number of items that have been collected after d days would be

4d + 5 + 3d + 7

= 4d + 3d + 5 + 7

= 7d + 12
