I need some help evaluating

Consider the following region R and the vector field F. a. Compute the two-dimensional divergence of the vector field. b. Evaluate both integrals in Green's Theorem and check for consistency F - (-3x, - 3y); R-(xy):x2+y =9 a. The two-dimensional divergence is -6 . (Type an exact answer.) Evaluate these integrals and check for consistency. Select the correct choice below and fill in the answer box(es) to complete your choice (Type an exact answer.) A. The integrals are consistent because they both evaluate to O B. The integrals are not consistent. The double integral evaluates to but evaluating the line integrals and adding the results yields
