You have enough paint to cover 300 square feet of fence. if the fence is 4 feet high, what length can you cover? you know the area (a = 300 ft2) and the width (w = 4 ft), but not the length. the formula would be more useful if it were rewritten to solve for the length in terms of the area and width. rewrite the formula by dividing both sides by the width. use the formula to find the length of fence (in feet) that can be painted. whats the length

Someone answer this asap rn 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)) =
