Answer:
$13.40
Step-by-step explanation:
First you subtract the lax from the total cost of the CDs then you divided that total by the number of CDs which is 6.
84.60 - 4.20 = 80.40
![\sqrt[6]{80.40}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B80.40%7D)
= $13.40
2(-3)(-5)(0)(-5)(-8)(3) = 0
It doesn't matter how many other numbers you multiply, anything multiplied by 0 will be 0.
No because to be symmetrical it would have to be cut in a way that it would look the same on both sides of the line and there is no way to do that with the letter L
2/x + 1/7 = 4/x
2/x + 4/x = -1/7 move the terms
Transform the expression
-2/x =-1/7 change the signs
2/x = 1/7 cross multiply
Final answer X= 14
