Can you help me with that please.

6. [8 pts] Calculate the surface integral of F = over the surface given by 3x 4 y + z = l, 0 S x, y S l, with an upward-pointing normal. 7. [8 pts] Use the divergence theorem to compute the ux of 13 : (3x,z, y + 2x) through the boundary of the region contained between a cylinder centered at the origin with a radius of 3, the plane 2 = x + 1 and the Ajv plane (be sure to look at your solidl)
