BẠN THAM KHẢO BÀI CỦA MÌNH NHA!!!!!

My neighborhood is located in a peaceful suburb of Dong Nai. It's a quiet and friendly place to live. Most of the houses here are small and have beautiful gardens. The people in my neighborhood are very kind and helpful. They often organize community events and gatherings. There is a small park at the end of the street where children love to play. I really enjoy living in my neighborhood because it's a safe and comfortable place to call home.

175 x 70 + 65 x 100 + 175 x 39 - 175 x 9

= 175 x (70 + 39 - 9) + 65 x 100

= 175 x 100 + 65 x 100

= 100 x 240

= 24000
