Hey there!
This can be written as
This is in form of
, it can be expanded as
=> (n-7)(n+7)=0
=> n -7 = 0 or n + 7 = 0
=> n = 7 or n = -7
So option 7 , -7 are correct.
Hope this is clear :)
Have a good day:)

If BA is d units the CB must be 2d units. B is on the x-axis, 2d units
right of C so its coordinates are (2d, 0). A is d units above B at (2d,
d). </span>

Answer:
A
Step-by-step explanation:
Here as we can see that minimum drink a person can drink is 0 and is
(3.5-0)/2 =1.75 std deviation away from mean
which reflects that distribution;s right tail is more extended
therefore option A is correct: Distribution is right skewed
