Aconstruction company has adjoined a 2000 ft^2 rectangular enclosure to its office building. three sides of the enclosure are fenced in. the side of the building adjacent to the enclosure is 200 ft long and a portion of this side is used as the fourth side of the enclosure. let x and y be the dimensions of the enclosure, where x is measured parallel to the building, and let be the length of fencing required for those dimensions. (a) find a formula for in terms of x and y. ,y)= x+2y (b) find a formula that expresses as a function of x alone. )= x+(4000/x) (c) what is the domain of the function in part (b)?

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
