    Option b and option f

    Step-by-step explanation:

    -6 (3x - 7) = - 18x + 42 so we will check for of the given options if they are equal to this.

    a. - 18x - 7 - --> NO

    b. 4 (3x + 5) - 2 (15x - 11) = 12x + 20 - 30x + 22

    = - 18x + 42 - --> YES

    c. 2x - 7 - 5 (4x - 7) = 2x - 7 - 20x + 35

    = - 18x + 28 - --> NO

    d. 4 - 10 (3x - 7) = 4 - 30x + 70

    = - 30x + 74 - --> NO

    e. 6 (3x + 7) = 18x + 42 - --> NO

    f. - 2 (9x - 21) = - 18x + 42 - --> YES

    Therefore, options b and f are equivalent to - 6 (3x - 7).
