Answer:
1st problem:
-1, 2i, -2i
Set the function equal to 0 and divide for x
0=x^3+x^2+4x+4
Subtract 4 from both sides leaving you with
-4=x^3+x^2+4x
divide both sides by four
-4÷4= -1
That is how you get -1
you now have -1=x^2+x^3+x
Solve for x buy finding the square roots of x^2, x^3 and subtracting x from both sides and you get 2i, -2i
Your answer to number one is -1, 2i, -2i
Second problem:
Find the LCD to be able to add these first
The LCD of (x-4)/x^2-2x is
x(x-2)
That is the first side done
The second side's LCD is (x+2)(x-2)
Now you can add the two together
x(x-2)+(x+2)(x-2)=
Your answer in fraction form is
(x+4)/x(x+2)
Answer:
18
Step-by-step explanation:
24 / 4 is 6 6 times 3 is 18

Step-by-step explanation:
Jayla has a couple of options for cutting her original piece of paper.
- she can cut the 3 inch length from the long dimension of the paper, giving her 5 strips from the length and 4 strips from the width for a total of 20 3×2 pieces
- she can cut the 3 inch length from the short dimension of the paper, giving her 3 strips from the 9-inch width, and 8 strips from the 16-inch length, for a total of 3×8 = 24 pieces.
The greatest number of 3×2 pieces Jayla can cut is 24.

Step-by-step explanation:
1.
√2 • √3 • √3 = 4.242640687119285
3√2 = 4.242640687119285
2.
√2 • √3 • √-3 = 4.24264069i
3i√2 = 4.24264069i
3.
√-2 • √-3 • √-3 = -4.24264069i
-3√2 = -4.24264069i
4.
√2 • √-3 • √-3 = -4.24264069i
-3i√2 = -4.24264069i
