I'm unable to directly transcribe text from images. However, I can help explain the concept you're working with—dashes in the Russian language. These are often used to separate parts of compound words or expressions. If you list them out clearly in text, I could help fill in the blanks with the appropriate dashes (e.g., hyphens, en dashes, or no dash needed). If you provide any specific questions or need explanations on the correct usage, feel free to ask!
