Question

Evaluate the expression, if x=12, y=8, and z=3 2xy-z3/z

Answer 1

Well if we are given numbers all we have to do is plug those numbers in for the variables. So we would have

2(12)(8)-3(3)/3

192-3
189

Answer 2

183

Explanation:

Evaluate the expression, if x=12, y=8, and z=3 2xy-z3/z

`2xy - (z^3)/(z)`

Plug in all the values in the values in the given expression

x=12, y=8, and z=3, Replace all the values

`2xy - (z^3)/(z)`

`2(12)(8) - ((3)^3)/(3)`

`192 - (27)/(3)`

`192 - 9`
