    3^2 = 9 4^2 = 8 9 + 8 = 17 What does that have to do with the original problem?

    42 divided by 8 = 5.25 so 5.3 (rounded to the nearest tenth) 42 divided by 9 = 4.6 so 4.7

    That's the closest I can come to the answer. I'm not quite sure what to do next nor how that connects to the answer exactly. I hope I helped you out a little bit.
