You can't cut and paste text from an image. You could edit the image and crop it so that you only get the text but it's not possible to paste it into Word as text, you would need to insert the cropped image into Word.
You might be able to run OCR (Optical Character Recognition) software against the image and it MIGHT be able to extract the text. OCR software often comes packaged with a scanner so if you have a scanner it may have included OCR software. If not, there are free OCR packages dfor download or even websites that you can upload the image to and run an OCR scan. Use your favorite search engine and search for "OCR software".
