Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
1) equation given: 0 = x^2 - 6x + 4
2) transpose 4: - 4 = x^2 - 6x
3) complete squares: - 4 = (x^2 - 6x + 9) - 9
4) transpose -9 and factor the square trinomial x^2 - 6x + 9:
- 4 + 9 = (x - 3)^2
5) combine like terms: 5 = (x - 3)^2
6) take square root on both sides: x - 3 = +/- √5
7) transpose - 3: x = 3 +/- √5
Answer: the two solutions are x = 3 - √5 and x = 3 + √5

Answer:
$15.95
Step-by-step explanation:
M= S - N
S= N + M
S = $6.54 + $9.41
It will take Mallory 40 minutes to get to the airport by train.
Step-by-step explanation:
Given,
Time taken by car = 120 minutes
Time taken by train = t
According to given statement;
Time taken by car = 3 times time taken by train
Dividing both sides by 3
It will take Mallory 40 minutes to get to the airport by train.
