7. (10 points) Choose, refer and use one of the theorems of Vector Calculus to evaluate the line integral F . ds as a double iterated integral where F(x,y) = ( 6x y' + 9x2 - Ary, -Ary - 212 - 4y -322, -6yz - 2) and C is a curve starting at the point (-1, 3, 2) and ending at the point (2, 0, -3). PLEASE make sure to write the name of the theorem to receive full credit
