If x, the time (in minutes) to complete an oil change at a certain auto service station, is uniformly distributed over the interval 20 to 30, inclusively (20 ≤ x ≤ 30), then the probability that an oil change is completed in 25 to 28 minutes, inclusively, i. e., p(25 ≤ x ≤ 28) is

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)
