Answer:
C) 0
Step-by-step explanation:
The opposite of 0 is 0.
You need to bring the right to the left
2X^2-9x-x^2+20=0
So you combine and get
X^2-9x+20
(X-4)(X-5)
Cuz -4 times -5 =20 and -4+-5=-9
So solve X-4=0. X-5=0
X=4. X=5
Formula for compound interest is
Interest = Amount - Principal
Interest = 
- P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = 
- 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = 
- 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
Answer:
Step-by-step explanation:
Well, first you need to find out what the time between 1st and 2nd is. It is 1 hour and 50 mins. But, then 2nd and 3rd, is 1110-1050 is 60 or 60 mins or 1 hour! Altogether, the 4th and 5th would be 12:20 for 4th and D for 5th
