Answer:
(x+2)^3=x^3-6x^2+12x-8
Step-by-step explanation:
Answer:
does not represent a function
Step-by-step explanation:
is not liner
Take out common factor, 3 :
3x - 3 = 3(x - 1)
------------------------------------
Answer: 3(x - 1)

Answer:
Let L be the length of the rectangle and w be the width of the rectangle.
"The lenght of a rectangle is one less than twice the width" means L=2W-1
Using perimeter formula of a rectangle which is P=2(L+W) you have:
P=2(L+W)
130=2(2W-1+W)
Solve equation above to find W
130=2(3W-1)
130=6W-2
130+2=6W
132=6W
W=22
From here you find L=2W-1=2x22-1=43
Only thing left is to find area A=LxW
First divide by 2
|x+1/4|=3
Then you pick the possible answers
|x+1/4|=3
|x+1/4|=-3
2 3/4 or -3 1/4
