A city planner designs a park that is a quadrilateral with vertices at J(-1,1), K(1,3), L(5, -1), and M(-1, -3). There is an entrance to the park at the midpoint of each side of the park. A straight path connects each
entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane represents 10
meters, what is the total length of the paths to the nearest meter? Round your answer to the nearest
whole number.

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)) =
