Answer:

Right option is B.

Step-by-step explanation:

$\sf \longrightarrow \frac{ \sec x \sin( - x) + \tan( - x) }{1 + \sec( - x) } \\ \\ \sf \longrightarrow \frac{ \sec x( - \sin x) - \tan x}{1 + \sec x} \\ \\ \sf \longrightarrow \frac{ - \frac{1}{ \cos x } \times \sin x - \tan x }{1 + \sec x} \\ \\ \sf \longrightarrow \frac{ - \tan x - \tan x}{1 + \sec x} \\ \\ \sf \longrightarrow \frac{ - 2 \tan x}{1 + \sec x} \\ \\ \sf \longrightarrow \frac{ \frac{ - 2 \sin x}{ \cos x} }{1 + \frac{1}{ \cos x} } \\ \\ \sf \longrightarrow \frac{ \frac{ - 2 \sin x}{ \cos x} }{ \frac{ \cos x + 1}{ \cos x} } \\ \\ \boxed{ \sf{\longrightarrow \frac{ - 2 \sin x}{ \cos x + 1} }}$

What is the value of 9(n+2)−5n for n=14? 3 9 10 19

Murrr4er [49]

If you want to know the value of a function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

9(14+2)−5*14

first calculate the inside of the bracket:


9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!

Perhaps you mistyped the questions? can you check it again, please?
