Alright, lets get started.
Height of the bin = 4 ft
Length of the bin = 9 ft
Width of the bin = 11 ft
Volume of the bin = 
Volume V 
Volume V
cubic feet
6 books fiils 1 cubic feet
or
1 cubic feet is filled by = 6 books
So, 396 cubic feet is filles by 
So, 396 cubic feet is filles by
books
It means 2376 books will fit in the storage bin. : Answer
Hope it will help :)
2x-4(x+1)=-13
1) we solve this equation:
2x-4(x+1)=-12
2x-4x-4=-12
-2x=-12+4
-2x=-8
x=-8/-2
x=4
2) we evalute x²-1
x²-1=4²-1=16-1=15
Answer: 15
Let's forget for the tie being the cost ($3.5)of the 1st fifth of a mile:
Taxi charge excluding $3.5, is $13.95 - $3.5 = $10.45.
If each of the 5th (1/5) of a mile costs $0.55, then with $10.45 we can drive:
10.45/0.55 = 19 fifth of a mile. Add to that the 1st fifth = 20 fifth of a mile
20 fifth = 20 x 1/5 = 4 miles (answer)
