okay, We know that Delta acts. In other words, changing axes. One of her on and a zero knew the formula for Delta X's B minus over end. So Bemis here, over, and somebody we know A is zero, which gives us one of her and therefore we know the hostage equivalent to one. Therefore, what we know is that we have the integral from zero 21 of X the fourth plus ax detox integrate increase the exploited by one divide by the new exponents increase to divide by two. Our solution is seven tons.
