2x +8=2(x + 4)
mutiply the bracket by 2
(2)(x)= 2x
(2)(4)= 8
2x+8= 2x+8
move 2x to the left side
sign changes from +2x to -2x
2x-2x+8= 2x-2x+8
0+8= 0+8
8= 8

Answer:
The box plot will have its left tail longer than the right tail becuase a few exceptionally low prices make the distribution skewed to the left.
Step-by-step explanation:
As seen in the attached file, the box plot has its left tail longer than the right tail because of the exceptionally low prices that is :$2
Firstly arranging the data in increasing order:
$2,$2,$25,$25,$26,$26,$27,$27,$28,$28,$30
Median of the data = 26 (since there are odd numbers)
Lower quartile (Q1) = 25
Upper quartile (Q2) = 26
By plotting the box plot we conclude that the left tail is longer than the right tail.
Answer:
SU=25
Step-by-step explanation:
We can set up a ratio as STU and SQR are similar because of the SAS similarity theorem.
TQ:SQ
SQ=ST+TQ=10+6=16
6:16=3:8
Therefore the ratio of STU:SQR is 3:8
We can use this to find SU
UR:SR=3:8
15:SR=3:8
Cross multiply
3SR=120
SR=40
SU=SR-UR
SU=40-15
SU=25
