D(x) is the price, in dollars per unit, that consumers are willing to pay for x units of an item, and S(x) is the price, in dollars per unit, that producers are willing to aocept for x units. Find (a) the equilibrium point, (b) the consumer surplus at the equilibrium point, and (c) the producer surplus at the equilibrium point. D(x)=(x6)2, S(x)=x2+2x+8 (a) What are the coordinates of the equilibrium point? (Type an ordered pair.)
