Correct each of the following errors by circling the error, describing what is wrong, entering what should be there instead, and entering the correct answer. 1. (3x^2)(-2x^4) = 3(-2)x^2•4 = 6x^8
2. 4a^2 • 3a^5 = (4 + 3)a^2 + 5 = 7a^7
3. x^6 • x • x^3 = x^6+3 = x^9
4. 3^4 • 2^3 = 6^4+3

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)) =
