Multiply and simplify
cot x (sin x + sec x)

Okay. Just to make sure, cot x  = cos x / sin x.

1) So, once cot x is distributed to sin x, then the sin x will cancel out the sin x from the cot x (which I showed you above) and you will be left with just cos x.

2) Once cot x is distributed to sec x (which can be also written as 1 / cos x), the cos x from cot x will cancel out the cos x from sec x.

3) Once you do that, your final answer will be: cos x + (1 / sin x )

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
