Question

is there anyone that can solve this for me and tell me how they came up with the answer?? (pic included)

Answer 1

So to begin, substitute all of the variables in for their corresponding value.

X=3
Y=-5
Z=-1

2XY+6YZ^2
2(3)(-5)+6(-5)(-1^2)
-30+-30
-60

Hopefully this is what they're asking for!
