In /slanted rectangle/ABCD, AE =7x - 1, and EC = 5x + 5
what kind of parallelogram is ABCD? Explain plz

ABCD is a //gram (parallelgram), so diagonal lines bisect each other, or AE = EC
7x - 1 = 5x + 5
2x = 6
x =3
AE = EC =20
AC = AE + EC = 40
ABCD is still just a parallelgram, not know to be a rectangle or not. Needs more info given

It is probably a rhombus, a parallelogram with sides of equal length.

Already answered this. Why do you continue to ask a question that has insufficient data to answer it and is improperly stated?
