Math question see if you're able to ! *plz explain*

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

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
