Answer:
Step-by-step explanation:
Give that:
the surface equation is 
from the family of traces in x = n given that , the equation can be represented as :
This represents a family of hyperbola for all values of n expects that n = ± 1
So, if n = ± 1,
Then
(y-z) (y+z) = 0
y = ± z
So, for n = ± 1, it is a pair of line for y = z, y = -z

(a-b)(a+b) because when you reverse the sum you do axa and ax-b xx
10/24 x 100 = 41.66
Approximately 42% of her day
First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
