I'm going to do this the long way, finding everything, but there are shorter methods if all you are trying to do is order n^2. I'm also going to start by removing the brackets in each question.

A

- 5n^3 + 5n^2 + 5 + n^3 - n^2

-4n^3 + 4n^2 + 5

B

n^3 + 2n^2 - n - 2 - (n^3 - 3n^2)

n^3 + 3n^2 - n - 3 - n^3 + 3n^2

5n^2 - n - 2

C

n^2(n - 4)+ 5n^3 - 6

n^3 - 4n^2 + 5n^3 - 6

6n^3 - 4n^2 - 6

D

2n^3 - 4n^2 - 2n + 3n^2

2n^3 - n^2 - 2n

The correct order is bad C or B A D C.

I don't know what to put into the boxes. You might have to ask about that.

The numbers in front of the coefficients for x^2 are

B = 5

A = 4

D = - 1

C = - 4

d = 16.76 inches

Step-by-step explanation:

We can extend the definition of the Pythagorean theorem to 3-dimensions:

d =  \sqrt{ {x}^{2} +  {y}^{2}  +  {z}^{2}  }

Let x = 10 in

y = 10 in

z = 9 in

d =  \sqrt{ {(10)}^{2} +  {(10)}^{2}  +  {(9)}^{2}  }

d =  \sqrt{281}  = 16.76 \: in
