    Number of students selected from University A:

    f (x) = 4x+5

    Number of students selected from University B:

    g (x) = 2x+8

    So total number of students selected from both universities:

    h (x) = f (x) + g (x)

    Put values

    h (x) = 4x+5+2x+8

    h (x) = 6x+13

    Option D is correct.
