Cece is building structures out of toy blocks of different sizes. She uses the diagrams and the measurements shown below. Structure 1 is made up of blocks that measure 1 cubic inch. Structure 2 is made up of Block A and Block B. Part A
Which structure has a larger volume and by how many cubic inches?

Part B
Cece builds a new structure that has twice the volume of Structure 2. It is made up of two blocks, Block C and Block D. What could be the dimensions of Block C, and what could be the dimensions of Block D?

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)) =
