nowymi
"Nowymi" means "new" in the instrumental plural form in English.
The word 'nowymi' here is the instrumental plural form of 'new (nowy)', used because the verb 'potrzebować' governs the instrumental case.
Mam nowe książki, ale potrzebuję pomocy z nowymi zadaniami.
I have new books, but I need help with new tasks.
'Nowymi' follows 'z', which requires the instrumental case to denote 'with' as a preposition.
Rozmawiałam z nowymi kolegami w pracy.
I talked with new colleagues at work.
The use of 'nowymi' complies with the noun 'możliwościami' in plural instrumental, demonstrating its agreement in the sentence.
