Answer:
$174.72
Step-by-step explanation:
105.88+43.50+36.61+92.78-38.19-65.86=174.72
An equation for that would be.
x => 67
C. 0.04 would be the correct answer.
3x² - 21
Factor 3 from both terms:
3 (x² - 7)
To me, that's as far as you should need to go. But if you want to get
completely carried away, you could go one step further, since you have
the difference of two squares:
3 (x + √7) (x - √7)
Of course, there's no end now, because the last binomial could be
considered another difference of two squares, so you'd have to
factor that too:
3 (x + √7) (√x + ⁴√7) (√x - ⁴√7)
but to me, this would be nonsense.
