Answer:
A=z
B=-2
C=0
D=30
Step-by-step explanation:
First lets simply the equation
21 - (2x +3)2 + 4(1-1) + z^3
21 - (2x^2 + 9) + 4(0) + z ^3
21 - 2x^2 + 9 + z^3
- 2x^2 + z ^3 + 30
This means that:
A=z
B=-2
C=0
D=30
Assume widthis x-2
perimeter is 2*(width+length)
so 2*(x+x-1)>112
2*(2x-1)>112
4x-2>112
x>28.5
so any length greater than 28.5 will work
Imaginary numbers ? just equate the imaginary with imaginary and real with real

1. So you have 2 1/2 and you want to find 1/5 of it. First, convert them to decimals.
2. Now you have 2.5 and need to find .2 of it
3. Multiply 2.5 by .2 to get your answer
4. Convert back to a fracton, your answer is 1/2
