Suppose R is the triangle with vertices (-1,0), (0, 1), and (1, 0).
(a) As an iterated integral, \iint_R (8x + 5y)^2 dA = \int_A^B \int_C^D (8x + 5y)^2 dx dy with limits of integration
A =
B =
C =
D =
(b) Evaluate the integral in part (a). Hint: substitution may make the integral easier.
Integral =
