The sum of three consecutive even integers is equal to 84. Find the numbers

Let the first even integer be x, Then the next even
integer is (x+2) and the third is (n+4).


Given that the sum
of the three even integers is 84.


Then we will rewrite into
an equation as follow:


n + (n+2) + (n+4) =
84


Now we will combine like
terms.


==> 3n + 6=
84


Now we will subtract 6 from both
sides.


==> 3n = 78


Now
we will divide by 3.


==> n=
26


==> n+2 =
28


==> n+4 =
30


Then, the three consecutive even integers
are 26, 28, and 30.

Can (sec x - cosec x) / (tan x - cot x) be simplified further?

Given the expression ( sec x - csec x ) / (tan x - cot x) We need to simplify. We will use trigonometric identities ...
