Okay this is the last one i already know how to distribute and such i was just wondering what's my next step

The next step after distribution is isolating the terms with the variable at one side and the terms with no variables at the other. Then solve to get the variable.
-2a+32 = -24a-40-2a
-2a+24a+2a = -40-32
24a = -72
a = -3

Only opposite sides are parallel.

Both opposite sides and opposite angles are congruent.

Step-by-step explanation:

They are both quadilaterals.

Properties of a parallelogram:

opposite sides congruent

opposite angles congruent

opposite sides parallel

diagonals bisect each other

while for a rhombus,

diagonals are perpendicular

all four sides are congruent
