We need to make sure the radical is defined, meaning the radicand has to be non-negative. Thus,

Thus, the domain in interval notation is 
Answer:
a) 7z³+2z²-2z+1
b)2x²+3x-8
Step-by-step explanation:
a) (7z³+4z-1)+(2z²-6z+2)
7z³+2z²-2z+1
b) (5x²-2x-1)-(3x²-5x+7)
5x²-2x-1-3x²+5x-7
2x²+3x-8
104*.75=78
78/8=9.75(divide by 8 because 80%/8=10%)
9.75*10=97.5
97.5*.8=78
75% of 104 is 78 which is also 80% of 97.5
Your answer is 97.5
