1. Original dimensions of the rectangle: \((2y) \times (y-7)\)
2. Remove a 1-inch by 1-inch square from each corner, which subtracts 2 inches from each dimension.
3. New length:\(2y - 2\)
4. New width:\(y - 7 - 2 = y - 9\)
5. The area of the remaining rectangle:\((2y - 2)(y - 9)\)
Answer:
(2y - 2)(y - 9)
2. Remove a 1-inch by 1-inch square from each corner, which subtracts 2 inches from each dimension.
