Surface Area, eh?
So, to solve this, you need to understand that Surface Area is just the added areas of the faces that make up the figure!
So, we just find all the areas of the faces, add them together, and there you go!
Let's solve!
![SA=(14*10)+2(25*10)+2(\frac{24*14}{2})](https://tex.z-dn.net/?f=SA%3D%2814%2A10%29%2B2%2825%2A10%29%2B2%28%5Cfrac%7B24%2A14%7D%7B2%7D%29)
So, there is our equation!
Wondering how I got it? Follow along!
I got (14*10) with that rectangle on the end of that rectangular prism, simple, as the area is just the multiplication of the lengths of the sides.
Now, same thing with 2(25*10), but why did I multiply by 2? It is because there is an identical face on the other side.
I also got 2(24*14/2) with the area of a triangle formula as the altitude is 24m. if you don't know what that is, might want to check google!(I also multiplied it by 2 because there was another identical face on the other side).
So, now that you understand where I am coming from, let us solve!
![SA=140+500+336\\SA=976](https://tex.z-dn.net/?f=SA%3D140%2B500%2B336%5C%5CSA%3D976)
More accurately, it is 976 m^2!
So, there you have it!

Adios!
The segments AE, EC, AD and DB are in proportion.
Therefore we have the equation:
![\dfrac{CE}{BD}=\dfrac{AE}{AD}](https://tex.z-dn.net/?f=%5Cdfrac%7BCE%7D%7BBD%7D%3D%5Cdfrac%7BAE%7D%7BAD%7D)
AE = 4ft, AD = 8ft and BD = 2ft. Substitute:
<em>multiply both sides by 2</em>
![CE=\dfrac{1}{\not2_1}\cdot\not2^1\\\\\boxed{CE=1\ ft}](https://tex.z-dn.net/?f=CE%3D%5Cdfrac%7B1%7D%7B%5Cnot2_1%7D%5Ccdot%5Cnot2%5E1%5C%5C%5C%5C%5Cboxed%7BCE%3D1%5C%20ft%7D)
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
![x+2y > 4](https://tex.z-dn.net/?f=x%2B2y%20%3E%204)
Isolate the variable y
subtract x both sides
![2y > -x+4](https://tex.z-dn.net/?f=2y%20%3E%20-x%2B4)
Divide by 2 both sides
![y > -\frac{1}{2}x+2](https://tex.z-dn.net/?f=y%20%3E%20-%5Cfrac%7B1%7D%7B2%7Dx%2B2)
The solution of the inequality is the shaded area above the dashed line
![y=-\frac{1}{2}x+2](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B1%7D%7B2%7Dx%2B2)
The slope of the dashed line is negative
The y-intercept of the dashed line is (0,2)
The x-intercept of the dashed line is (4,0)
therefore
The graph in the attached figure
7 cups of flour ... 9 people
x cups of flour = ? ... 15 people
If you would like to know how many cups are needed to make a cake for 15 people, you can calculate this using the following steps:
7 * 15 = 9 * x /9
x = 7 * 15 / 9
x = 35/3
x = 11 2/3 cups of flour
Result: 11 2/3 cups of flour are needed to make a cake for 15 people.
