hi! can you please help me out with these problems?

(1 point) Consider the area between the graphs x + 2y = 31 and x + 4 = y" . This area can be computed in two different ways using integrals First of all it can be computed as a sum of two integrals g(x) dx where a = ,b = and f ( x ) = g(x) = Alternatively this area can be computed as a single integral B h(y) dy where a = , f = and h( y) = Either way we find that the area isA solid lies between planes perpendicular to the x-axis at x = 0 and x = 5. The cross-sections perpendicular to the x-axis on the interval 0
