Answer:
length=24 inches and width=12 inches
Step-by-step explanation:
Let width of the rectangular sheet be x.
Then its length is twice as width = 2x
From each corner 3-inch square is cut to form a tray.
The length of the tray formed = l = 2x-6 (total length - length of 2 squares cut out from both ends)
The width of the tray formed = b = x-6 (total width - length of 2 squares cut out from both ends)
Height of the tray formed = h = 3 inches
Volume of the tray = l*b*h = (2x-6)*(x-6)*3 = 324 cubic inches.
The length and width of the sheet is 24 and 12 inches respectively.
The original area of the rectangle is 
<u>Explanation:</u>
width = x
length = x + 2
area of the rectangle = x (x+2)
length = x + 2 + 5 = x+7

Solving this equation, we get
x =5ft
So, original width = 5ft
original length = 5+2ft = 7ft
Thus, original area of the rectangle = 5 X 7ft = 
Therefore, the original area of the rectangle is 
Answer:
22

Answer:
15x
Step-by-step explanation:
because i multiply i side by side and copy the variable
Okay so this problem basically is saying if the value is 90000 and per every 1000 she has to pay 31$ in tax
So first divide $90,000 by $1,000 you should get 90
Now you can do 90 times $31 to find how much tax she will have to pay which equals $2,790 tax total
