    Dear mcdeagon,

    Answer to your query is provided below:

    Magnitude of - 2a-3b = - 18i-6j

    Step-by-step explanation:

    When a = 3i+9j and b = 4i-6j

    Magnitude of - 2a-3b will be calculated by putting value of a and b

    So, - 2a-3b = - 2 (3i+9j) - 3 (4i-6j)

    = - 6i-18j-12i+12j = - 18i-6j
