    D. sqt5

    Step-by-step explanation:

    The best process is to start eliminate answers. It can not be C because

    -8 + 8 = 0. 0 is not an irrational number. Sqt4 is 2, 2+8=10. 10 is a real rational number. 5/9 is not an irrational number because it is a ratio of 5 to the non-zero quotient of 9. Sqt5 is the only irrational number, and when added to 8, it is still irrational.
