Hello from MrBillDoesMath
Answer: -4x^3 + 8x^2 -5x + 12
Discussion:
Standard for for a polynomial meas tne power of x descend so standard fro of
8x^2 - 4x^3 +12 -5x is
-4x^3 + 8x^2 -5x + 12
Note: the problem statements shows this ":8x^2". I didn't know how to deal with the ":" character so simply ignored it.
Thank you,
Mr. B
This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours

Answer:
C 1/2
Step-by-step explanation:
There are 4 suits, 2 suits are red (hearts and diamonds) while 2 are black (clubs and spades)
Since 13 cards are in each suit, 26 cards are red ( 2 * 13)
There are 52 total cards
P (red) = red cards/ total cards
= 26 / 52
= 1/2
