x = number of weeks.
When you plug in the number of weeks for x you'll get the amount of hours she had for dance classes.

3x
3(3)
= 9(She had 9 hours of dance class combined for the past three weeks).
Answer:
2nd option
Step-by-step explanation:
The discriminant b² - 4ac tells us about the nature of the roots
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then the roots are not real
Here b² - 4ac = 15 > 0
Then there are 2 real and distinct roots
x = 2 and x = - 3 are possible solutions to the equation
