Answer:
The answer to your question is the last option
Step-by-step explanation:
Quadratic equation
2 = - x + x² - 4
Order the equation from the highest power to the lowest power. Do not consider 2 because it is not consider in the options given.
x² - x - 4 = 0
Identify a, b and c
(1) x² -(1) x - 4 = 0
a = 1 b = -1 c = - 6
Substitution

Step-by-step explanation:
Simple interest , I, is calculated by multiplying the principal, P, by the rate,r, by the time, t, in years:
I = P * r * t
Here, P = $600
r = 0.05 (decimal value for 5%)
t = 2 years
Part a)
The interest earned will be:
I = P * r * t
I = 600 * 0.05 * 2
I = $60
Part b)
The balance in the account will be $600 plus the interest earned or:
$600 + 60 = $660
