Answer:
The surface area is 
Step-by-step explanation:
The surface area of a rectangular prism is calculated using the formula;
![S.A=2[lw+lh+wh]](https://tex.z-dn.net/?f=S.A%3D2%5Blw%2Blh%2Bwh%5D)
The length of the rectangular prism is
The height is 
The width is 
The surface area
![S.A=2[10(8)+10(6)+8(6)]](https://tex.z-dn.net/?f=S.A%3D2%5B10%288%29%2B10%286%29%2B8%286%29%5D)
![S.A=2[80+60+48]](https://tex.z-dn.net/?f=S.A%3D2%5B80%2B60%2B48%5D)


Answer:
John answered 50 questions.
Step-by-step explanation:
Although five of John's answers were incorrect, 90% of his answers were correct.
This means that 5 is 100 - 90% = 10% of the total number of questions, n. So

Answer:

Step-by-step explanation:
In a quadratic equation in the Standard form

You need to remember that "a", "b" and "c" are the numerical coefficients (Where "a" is the leading coefficient and it cannot be zero:
).
You can observe that the given quadratic equation is written in the Standard form mentioned before. This is:

Therefore, you can identify that the values of "a", "b" and "c" are the following:
