Answer:
Step-by-step explanation:
..
X^4+ 3x^3+4x^2-8 | x+2 = x^3+x^2+2x-4
-x^4-2x^3
-----------------------
x^3+4x^2-8
-x^3-2x^2
-------------------------
2x^2-8
-2x^2-4x
--------------
-4x-8
4x+8
----------------------------
/ /
is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
7) 2-9= -7 because, if you have two cookies and promised nine friends cookies, you would still owe 7 friends cookies or -7
8) -3 - (-4)= 1 because you owe 3 friends cookies, then you get 4 cookies and have one left over
9) 11 - (-12)= 23 because a negative plus a negative is a positive

Answer:
12 OR 1/12 (Check how you write your equations! Just look below for the one that it actually is lol)
Step-by-step explanation:
6 = (1/2)n
6/(1/2) = n
12 = n
OR
6 = 1/(2n)
6(2n) = 1
12n = 1
n = 1/12
