Calculate the iterated integral. (1 + Ary ) dx dy =Calculate the iterated integral. -2 (1 + Ary) dx dy art 1 of 2 When calculating J. J. (1 + 4xy) dady, we find the inner integral first. Since this is an integral with respect to x, then we consider x to be the variable and y to be a constant. Therefore, 2 (1 + 4xy) dx = x+ 0 = 2+Calculate the iterated integral. 2 (12x3 - 18x y' ) dy dix = 1Calculate the double integral. (12x y' - 10y ) dA , R= {(x, y)|0
