Answer: 6.25 IF my assumption is correct about the missing x!

The Other way around: 4.5 with 2x² + y² / 3

Step-by-step explanation: 2y² + y² / 3 assuming the 2nd y should have been x, 1st y is y, and all divided by 3

2(3)² + (1.5)² / 3

2(9) + 2.25 /3

18 + 2.25 /3

20.25/3

6.25

Edited to correct!________ OR 2y² + y² / 3 assuming the 1st y should have been x, 2nd y is y, and all divided by 3

2(1.5)² + (3)² / 3

2(2.25) + 9 / 3

4.5 + 9 /3

13.5 /3

4.5

Answer:


(13.5)/(3)

Explanation:

=>
2x^2+y^2/3

Where x = 1.5, y = 3

=> 2(1.5)²+(3)² / 3

=> 2(2.25)+9 / 3

=> 4.5 + 9 / 3

=> 13.5 / 3

=>
(13.5)/(3)
