    Write the set {t: |25+7|>5} as a union of two intervals

    {t: |25+7|>5} It's actually equal to or more than 5, but I don't know how to enter the code in this forum, so please bear with me.

    are you missing a factor of t somewhere within the absolute value?

    because |25+7| = |32| = 32 > 5 no matter what ...
