Answer:
n= 26, so the answer would be 'B'.
Step-by-step explanation:
n-8=18
n=18+8
n=26
Answer:
5 Degrees
Step-by-step explanation:
In order to find the median, you must put the temperatures in ascending order. The median is the number in the middle.
This week
65 71 73 73 73 74 75
Last Week
51 62 66 68 72 72 85
The median of This week is 73 while the median last week is 68.
73-68=5 degrees
A(-5,5)
B(4,5)
C(2,0)
D(-5,-2)
AB,BC,CD,DA
AB = [4-(-5)),5-5]=[9,0]

sorted from longest to shortest:
AB, CD,DA,BC
I’m fairly certain it is 70 , or option 4 :))
