Answer:


Step-by-step explanation:
A vector quantity is represented by 
where y = y-coordinate and x = x-coordinate
Since vector AB represents a vector in 3rd quadrant,
It starts from point A and ends at B,
Therefore, coordinates of B are (-9, -4)
= 
Similarly vector CD starts with C and ends at D in the 2nd quadrant,
Therefore coordinates of D will be (-5, 4)

Answer:
1 1/3
Step-by-step explanation:
m = y2-y1 over x2-x1
The perimeter of the parallelogram is 14x + 8. You add 3x+9+4x-5+3x+9+4x-5 to get the answer.
