Answer:
we need the actual problem
Step-by-step explanation:
please post a photo or just type out the question
The expression i determined is 10x + 6
Let w=width
L= length
3w+1=l
Perimeter -2(l+w)
2(W+3w+1)=42
Divide both sides by 2
W+3w+1=21
Subtract 1
W+3w=20
Add like terms
4w=20
Divide both sides by 4
W=5
The width is 5 inches
3w+1=l
Input the width into the equation
3(5)+1=l
15+1=l
16=l
The length of the rectangle is 16 inches
The rectangle is 5 x 16 inches
The later it happens, the bigger the fluctuations are. It was at 53.5 percent level at the begining, then it slightly dropped and again gained nearly as much as at the begining. Then it dropped very noticeably, then it broke a record in terms of both increase and max. percentage level, then it again broke a record, but this time in terms of decrease and min. percentage level. That's more less what I concluded from the line graph :)
