Answer: v=-18/5
Step-by-step explanation:
Assuming you want to solve for v, we need to use our algebraic properties.
[subtract both sides by 2]
[multiply both sides by 3]

Now, we know that v=-18/5.
The area of a parallelogram is base multiplied by height and therefore 18/2 and there you go.
Your answer is 12

Answer:
80
Step-by-step explanation:
The equation of finding a slope is y2-y1/x2-x1.
y-5/-7-(-21)=5
y-5/-7+21=5
y-5/15=5
y-5=75
y=80
