Answer:
The height is 6 - you will need to divide.
Step-by-step explanation:
volume = base times height
10 times height = 60
divide both sides by 10
height = 60/10
height = 6
The left hand side of the equation is a difference of two squares and may be factored out as follows,
(x - 4)(x + 4) > 0
They may be individually taken as,
x - 4 > 0 ; x > 4
x + 4 > 0 ; x < -4
Thus, the answer to this item is letter A.
