Could you please help me with this 3 question:

Evaluate the following iterated integral. 29 12y If dxdy=|:| o 4 ix'z {Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.) When converted to an iterated integral, the following double integral is easier to evaluate in one order than the other. Find the R 2x sec 2(xy)dA; R = {(x,y): Osxs -, 0sys3} Select the correct answer below and fill in the answer box to complete your choice. O A. It is easier to integrate with respect to x first. The value of the double integral is (Type an exact answer.) O B. It is easier to integrate with respect to y first. The value of the double integral is (Type an exact answer.)When converted to an iterated integral, the following double integral is easier to evaluate in one order than the other. Find the X R dA; R = {(x,y): Osxs4, 1sys2} (5 + xy)2 Select the correct answer below and fill in the answer box to complete your choice. O A. It is easier to integrate with respect to x first. The value of the double integral is (Type an exact answer.) O B. It is easier to integrate with respect to y first. The value of the double integral is (Type an exact answer.)
