Question

2x^2-y if x=3 and y=8

Answer 1

Answer:

= 10

Step-by-step explanation:

x = 3

y = 8

just replace that x and y with the values given

$2x^{2}$ - y

2 ($3^{2}$) - 8

2 (9) -8

18 - 8

= 10

Answer 2

The answer is 10
Because of PAMDAS you do 3 to the second power first which equals 9. 9x2 is 18. And then 18 - 8 = 10. In all, You just plug x and y in and then solve by PAMDAS.
