Answer:
Tyrell is in the lead by 2 points.
Step-by-step explanation:
Example:
Imagine they both started at 10 points. If Parline lost 5 points (10 - 5) while Tyrell lost 3 points (10 - 3), then it is clear that Tyrell's points (7 remainings) are more than Parline's points (only 5 remainings). Hence, Tyrell is in the lead by 2 points.
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.
Answer:
The correct answer is 8
Step-by-step explanation:
It’s 8, because 5- (-3) is like saying 5+ 3, because in math when your dealing with negatives, 2 negitives means the answer is positive and 1 negative means the answer is negative. Hope this helps! :)
Answer:
455
Step-by-step explanation:
They are not in proportion, since its 6:9 round it down (2:3) so pretend the 6 are apples and the 9 are oranges
Every 2 apples there are 3 oranges
So having 9 apples what is that?
2 x ? = 9
2 x 4.5 = 9
So if you want to keep 2:3 you have you times the oranges by 4.5 aswell!
3 x 4.5 = 13.5
So since it is 9:12 not 9:13.5 they are not in proportion
