Answer: 20!!!!

Step-by-step explanation: I got it right when I did it

Answer 2

20

Explanation:

Given,

X = 3

y = -2

Now,

`2 {x}^(2) - y`

Plugging the value of X and y

`2 * {(3)}^(2) - ( - 2)`

Calculate the product

`= 2 * 9 - ( - 2)`

`= 18 - ( - 2)`

`= 18 + 2`

`= 20`

Hope this helps...

Good luck on your assignment
