Answer: Inconvenient Social Medias
Explanation: Inconviniants ---> is a cognate meaning the spelling is similar in french and in english.
Reseaux ---> Medias - the "x" on the end implies that the word is plural
Sociaux ---> Social - even though "social" in this context can be an adjective, it still needs to agree with the noun, meaning - if the noun is singular, the adjective is singular.
Example - If the noun is feminine plural, the adjective is feminine plural. That's called agreements.
