The answer are both:
x=2+4i,2-4i
Answer:
-1 <= x <= 1
Step-by-step explanation:
√((1-2x+x^2)+2-2x^2)
= √((1-x)^2 + 2*(1-x)(1+x) )
điều kiện là 1 - x > =0 và 1+x >=0

Answer:
4 Hours.
Step-by-step explanation:
Since they charge $5 for every hour, we can use 5(x) as our first variable, x being the number of hours that he rented the paddle boar. Also, since they charge $8 up front, we have to subtract that from the total cost , so it would be $28 - $8. After this we divide the result ($20) by 5, since our coefficient is 5, and it costs $5 to rent it every hour. This results in 20/5, and comes out to 4 hours in total.
