In this problem we use the change of variables x=5s+tx=5s+t, y=s−ty=s−t to compute the integral ∫r(x+y)da∫r(x+y)da, where rr is the parallelogram with vertices (x, y)=(0,0)(x, y)=(0,0), (5,1)(5,1), (6,0)(6,0), and (1,−1)(1,−1).

The pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is find the pressure exerted when the temperature of the gas is 380 degrees f show work for the
