Answer:
12, 14, and 16
Step-by-step explanation:
These kinds of problems can be written as the equation x + (x + 2) + (x + 4) = s, where x = first integer and s = total.
Plug in s: x + (x + 2) + (x + 4) = 42
Associative property of addition: x + x + 2 + x + 4 = 42
Combine like terms: 3x + 6 = 42
Subtract: 3x = 36
Divide: x = 12
This means that the first integer is 12, and the rest are 14 and 16.
