Answer:
Step-by-step explanation:
length : 2x
width : 3x+2
Perimeter = 2(l+w)
substitute in knowns
74 = 2(2x+3x+2)
combine like terms
74 = 2(5x+2)
distribute
74 = 10x+4
subtract 4 from each side
70 = 10x
divide by 10
x=7
Answer x=10

Q3 = 21</h3>
The data is already sorted for us. If it wasn't, then you would have to write the values from smallest to largest.
The median is the middle most value 9 (in slot 4)
The median separates the data into two halves, which I'll call the lower and upper half
lower half = {4,6,8}
upper half = {13,21,31}
The median of the lower half is 6, and this is the value of Q1.
The median of the upper half is 21. This is the value of Q3
