    32 is the correct answer

    Step-by-step explanation:

    To evalute this expression we need to slot in the known value of the expression given thr

    x = 2

    y = 3

    z = - 4

    the question

    2z^2

    2 x z²

    = 2 x (4) ²

    = 2 x 16

    = 32

    therefore the value of 2z²2 when z is equal to 4 is evaluated to be 32
