No solution because the lines are parallel.
Answer:
6
Step-by-step explanation:
root the 216 as it is a cube
:edge *edge *edge =volume
Since all edges are the same, just root it

$84
$160 * 0.30 = $48
$160 - $48 = $112
$112. * 0.25 = $28
$112 - $28 = $84
Use what you know.
Guitar cost =$160 w/ 30% off
30% = 30/100 = 0.30.
30% off means 30% of the price $160 will be taken off so that is why I multiplied 160 by 0.30 (30/100).
30% of 160 is 48 so I subtracted 48 from 160 which equals $112.
With an extra 25% off I repeated the same steps above.
25/100 = 0.25
$112 * 0.25= $28
$112 - $28 = $84
If you need me to break it down more just let me know. I HOPE THIS HELPS
You know 1 is not a root because the sum of the coeffcients of the equation is 14, not zero.
It is fairly easy to try 3 by synthetic division (see attachment), which tells you that 3 is a root and the remaining quadratic factor is x²-3x-5. The quadratic formula tells you the roots of that factor are
... x = (-b±√(b²-4ac))/(2a) = (3±√29)/2
The appropriate choices are
... C. (3-√29)/2
... D. (3+√29)/2
... F. 3
_____
The quadratic formula tells you the solution to
... ax²+bx+c=0
is x = (-b±√(b²-4ac))/(2a)
We have a=1, b=-3, c=-5.
1. (3,-2)
2. (-2,2)
3. (1/3,2/3)
4. (13/7, 40/7)
