Evaluate the expression when x = 2, y = 3, and z = - 4.

2z^2

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

32

Step-by-step explanation:

2z^2

Let z = - 4

2 (-4) ^2

2 * (16)

32
