Question

You heard a noise ( chang into negative )​

Answer 1

Answer- Did you heard a noise?

Answer 2

Answer: You did not hear a noise

You did not hear a noice

here we changed the sentence to negative by adding did there, it could have been do not/does not but this sentence is written in past tense and the past tense of do is did so we use did there and then ofc the not

Hope this helped you in any way possible  ^-^

Marking as brainliest would be very nice of you.
