Find all solutions and write the answer in a general form. 6 sec2(x) − 6 = 0

x = pi n

Step-by-step explanation:

6 sec^2(x) − 6 = 0

Add 6 to each side

6 sec^2(x) − 6+6 = 0+6

6 sec^2(x)=6

Divide by 6

 sec^2(x)  = 1

Take the square root of each side

sqrt(  sec^2(x) ) = ±sqrt(1)

 sec(x)  =± 1

sec (x) = 1       sec(x) = -1

Take the inverse sec of each side

sec^-1(sec (x)) = sec^-1(1)       sec^-1(sec (x)) = sec^-1(-1)

x = 2 pi n                                    x = pi + 2 pi n   where n is an integer

Combining

x = pi n

or

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
