Is my answer correct or no?

the shape is NOT a rhombus, because opposite sides are parallel but not all sides are congruent in length.

This shape is instead a parallelogram, where opposite sides are parallel but all sides do not have to be the same length

if 2 pairs of opposite sides are parallel, then opposite sides must be congruent, changing the angles will create nonparallel opposite sides that are unequal length and neither a parallelogram nor rhombus

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
