Answer:
n = 16
Step-by-step explanation:
Answer:
4.
Step-by-step explanation:
Since Eve has already knitted nine scarves we just need to add of few more. Our equation is this: 9 + _ + _ = ?
If you do 9 + 4 + 4, you get 17. Therefor, Eve must knit four scarves per day to meet her goal.
Let's say that ground level is 0. When she goes down to the basement, she is going -12 feet since each flight of stairs is12 feet. Then she goes up 12 more feet= -12+12=0. She is back at ground level. Then she goes up another 12 feet= 0+12= 12. So I believe the answer is 12 feet.

Step-by-step explanation:
x^4+4y=8xy
=>8xy-4y=x^4
=>4y(2x-1)=x^4
=>4y=x^4/(2x-1)
differentiating both side we got
4 dy/dx={4x^3(2x-1)-2x^4}/(2x-1)^2
i.e, dy/dx=(6x^4-4x^3)/4(2x-1)^2
=(6x^4-4x^3)/(16x^2-16x+4)
