Do you know the Rational Roots Theorem? You could dream up possible rational roots by writing them in the form
plus or minus {1,2, 3,6} OVER plus or minus {1,2,5,10}. For example, 3/10 is rational and just might be a rational root. Next, determine whether or not this is a rational root here thru synthetic division.
If you do not know this theorem, consider using one of the following:
quadratic formula
completing the square
graphing (look for the x-values at which the parabolic graph here crosses the x-axis).
If Dave earns $150/week times 4 weeks = 600
3.8% commission on $4175.68 is $158.68
$600 + $158.68 = $758.68 for the month of February
The answer is true.
5.4 divided by 0.6 = 9
12.6 divided by 1.4 = 9
John is correct because 0.5 is equal to one half and multiplying something by its half is just same as dividing something in two and half of 1.4 is 0.5
