AB + CD = BC + DA
<span>Where A, B, C, and D are points on the quad, and AB is the length of the line A to B, etc. </span>
<span>Since you know three sides, you can easily solve for the fourth. </span>
Answer: 10 inches × 14 inches
Work:
length = x inches
width = x - 4 inches
perimeter = 2(l+w)
48 = 2[(x)+(x - 4)]
48 = 2(2x - 4)
24 = 2x - 4
28 = 2x
14 = x
length = x inches = 14 inches
width = x - 4 inches = 14 - 4 = 10 inches
The amount of kerosene and gasoline produced is an illustration of equations.
<em>44.4 million barrels of gasoline and kerosene are produced</em>
Let
<em />
<em> Proportion of kerosene</em>
<em />
<em> Proportion of Gasoline</em>
<em />
So:
![x = 40\%](https://tex.z-dn.net/?f=x%20%3D%2040%5C%25)
![y = 34\%](https://tex.z-dn.net/?f=y%20%3D%2034%5C%25)
---- total barrels produced
The amount of Kerosene produced is:
![Kerosene =x \times Total](https://tex.z-dn.net/?f=Kerosene%20%3Dx%20%5Ctimes%20Total)
![Kerosene =40\% \times 60\ million](https://tex.z-dn.net/?f=Kerosene%20%3D40%5C%25%20%5Ctimes%2060%5C%20million)
![Kerosene = 24\ million](https://tex.z-dn.net/?f=Kerosene%20%3D%2024%5C%20million)
The amount of Gasoline produced is:
![Gasoline =y \times Total](https://tex.z-dn.net/?f=Gasoline%20%20%3Dy%20%5Ctimes%20Total)
![Gasoline =34\% \times 60\ million](https://tex.z-dn.net/?f=Gasoline%20%20%3D34%5C%25%20%5Ctimes%2060%5C%20million)
![Gasoline =20.4\ million](https://tex.z-dn.net/?f=Gasoline%20%20%3D20.4%5C%20million)
So, the total production of both is:
![Total = Kerosene + Gasolene](https://tex.z-dn.net/?f=Total%20%3D%20Kerosene%20%2B%20Gasolene)
![Total = 24\ million + 20.4\ million](https://tex.z-dn.net/?f=Total%20%3D%2024%5C%20million%20%2B%2020.4%5C%20million)
![Total = 44.4 million](https://tex.z-dn.net/?f=Total%20%3D%2044.4%20million)
<em>Hence, 44.4 million barrels of gasoline and kerosene are produced</em>

Answer:
13
Step-by-step explanation:
We need to write our answer in exponential form. Ask yourself the question, "What times itself 3 times will give you 2197?" Your answer is
. This will go inside of your cube root. You now have
. Since there's a power of 3 and a cube root, those cancel each other out, and your answer is 13.
