Mya applied the distributive property to write the equivalent expressions below. 45 + 72 = 9 (5 + 9)

What is Mya’s error?
Mya did not write the common factor in the correct place.
Mya did not find the correct two factors for 72.
Mya did not find the correct two factors for 45.
Mya used a factor that is not common to 45 and 72.

If I get this wrong then I'm finna be mad cuz this is my exam.
