A shoe company is going to close one of its two stores and combine all the inventory from both stores. These polynomials represent the inventory in each store:

Store A:
$\frac{1}{2}g^2+\frac{9}{2}$

Store B:
$4g^2-\frac{3}{5}g+\frac{3}{4}$

Which expression represents the combined inventory of the two stores?
$\frac{9}{2}g^2-\frac{3}{5}g+\frac{21}{4}$
$\frac{9}{2}g^2+\frac{39}{10}g+\frac{3}{4}$
$-\frac{7}{2}g^2+\frac{3}{5}g+\frac{15}{4}$
$-\frac{7}{2}g^2+\frac{51}{10}g-\frac{3}{4}$
