Hello from MrBillDoesMath!
Answer:
9
Discussion:
Solution 1:
Distance between two points (x1, y1), (x2,y2) is given by the formula
sqrt( (x1-x2)^2 + (y1-y2)^2). In our case this becomes
sqrt( (0-0)^2 + (12 -3)^2 ) =
sqrt( 9^2) =
9.
Solution 2:
Note points D and E both have x = 0 so segment DE is a vertical segment. The length is simply the difference of the y coordinates: 12- 3 = 9 as before.
Thank you,
MrB

Y-5=9(x-1)
y-5=9x-9
answer: y=9x-4
Answer:
x = 60
Step-by-step explanation:
t = 
15 = k/68
k=1020
~~~~~~~~~~~
17 = 1020/x
x = 1020/17
x = 60
Number one is A because it has four sides, all of them are parallel, and it can be called a rectangle, a rectangle just cant be called a square.
Can't answer the other one. Sorry! Good luck!
Gotta go!
