Final answer:

The expression for Mike's age in terms of x is 3x + 4.

Step-by-step explanation:

To find Mike's age, we need to understand the given information:

  • Kate is x years old
  • Lethna is 3 times as old as Kate
  • Mike is 4 years older than Lethna

Since Lethna is 3 times as old as Kate, her age is 3x. And since Mike is 4 years older than Lethna, his age would be 3x + 4.

Therefore, the expression for Mike's age in terms of x is 3x + 4.
