That depends entirely on the value of x.

x3+3x2+3x+2 divided by x+2 equals x2+x+1

it has to have a value for you to do anything to it

9x2 + 3x / 3x equals (3x + 1).9x2 + 3x divided by x is 9x + 3 , and then divided by 3 yields the 3x +1.

- If 3X - 1 = 11, what is the value of X^2 + X?

Given a value of x, find the value for -3x + 2

An equation where x = -20

Presumably, this is an equation in finding the value of x 3x+5/4 = -2x+15 3x+1.25 = -2x+15 3x+2x = 15-1.25 5x = 13.75 x = 2.75

Ten. That means 3x equals 30, and 30 divided by three is ten.

5

Your equations are not worded properly.

3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.
