Answer:
Option C is correct.
Step-by-step explanation:
Let the length be L
Let the width be W
The length of a rectangular floor is twice its width.
So, we get 
The length of the carpet is L
Carpet width is 2 feet less than the room, so 
Area of the carpet = 160 sq feet
We get :
As L=2W, we get
=> 
Equating to zero, we have
Taking out 2 common
=> 
=> 
We get roots as : (W-10) and (W+8)
Hence, W = 10 and W = -8(neglect this negative value)
Now, the width = 10 feet
Length = 
feet
Hence, option C is the answer.
The answer to (-7)+1+4= -2
The answer would be 30 because, because there are 27-22 in extra parentheses we do that first which would be 5 then 100/5=20 because thats in the next set of brackets then -3*5 according to order of operations so now we have 20-15=5 then 5+25 because thats all thats left which is are end answer of 30=) Enjoy!=)
Remember that to find distance (or the slope) you need this formula y2-y1/x2-x1. 5+10 = 15
-3+9 = 6 15/6 = 5/2

Is ur answer
Answer:
1.8 = 18/10 = 9/5
0.2 = 2/10 = 1/5
