Answer:
there is the thing you need to answer the question right
Step-by-step explanation:
Expanded form means breaking the number into addition.
408,032,009 = 400,000,000 + 8,000,000 + 30,000 + 2,000 + 9
If their mean is 5, then the numbers add up to 25.
Here are a few sets that do the job:
1, 2, 3, 4, 15
10, 20, 30, 40, -75
+2, -2, +99, -99, 25
1, 5, 5, 5, 9
