Answer:
7.50
Step-by-step explanation:
To evaluate an expression for particular values of the variables, put those variable values in place of the corresponding variable and evaluate the resulting numerical expression according to the Order of Operations.
[tex]2x^2 +\dfrac{y^2}{3}\qquad\text{for x=1.5 and y=3}\\\\=2(1.5)^2+\dfrac{3^2}{3}\\\\=2(2.25)+\dfrac{9}{3}=4.50+3=\boxed{7.50}[/tex]
