Question

Please help, I have two questions that I need answers to for 25 points!

Answer 1

Answer:

1) 6+7=42$feet^{2}$

2) Beginning (0,0,-25) end (0,-20,-25)  

Step-by-step explanation:

1) Plot these point on graph. By this you can determine the fourth coordinate(-3,4) as it is a rectangle.

So, length =7

     breadth =6

area =7*6 =42$feet^{2}$

2) Here height of rack is 25 feet thus it's Z coordinate is -25.

  It moved 20 feet south along Y axis thus Y coordinate = -20

  No movement in X thus x coordinate =0

Thus , beginning (0,0,-25) end (0,-20,-25)
