Answer:
option b
Step-by-step explanation:
![{x}^{2} - 2x - 15](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20-%2015)
![{x}^{2} - 5x + 3x - 15 = 0](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%205x%20%2B%203x%20-%2015%20%3D%200)
![x(x - 5) + 3(x - 5) = 0](https://tex.z-dn.net/?f=%20x%28x%20-%205%29%20%2B%203%28x%20-%205%29%20%3D%200)
![(x - 5)(x + 3) = 0](https://tex.z-dn.net/?f=%28x%20-%205%29%28x%20%2B%203%29%20%3D%200)
x = -3 (Not possible)
x = 5
So, x = 5

Step-by-step explanation:
Answer:
x
Step-by-step explanation:
Using the trigonometric identities
1 + tan²x = sec²x and 1 - sin²x = cos²x
secx = ![\frac{1}{cosx}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bcosx%7D)
Given
![\frac{1-sin^2x}{1+tan^2x}](https://tex.z-dn.net/?f=%5Cfrac%7B1-sin%5E2x%7D%7B1%2Btan%5E2x%7D)
= ![\frac{cos^2x}{sec^2x}](https://tex.z-dn.net/?f=%5Cfrac%7Bcos%5E2x%7D%7Bsec%5E2x%7D)
= ![\frac{cos^2x}{\frac{1}{cos^2x} }](https://tex.z-dn.net/?f=%5Cfrac%7Bcos%5E2x%7D%7B%5Cfrac%7B1%7D%7Bcos%5E2x%7D%20%7D)
= cos²x × cos²x
=
x
Answer:
(a) What was the total of accounts written off during the first 11 months?
(b) As the result of a comprehensive analysis, it is determined that the December 31, 2010, balance of the Allowance for Bad Debts account should be $9,450. Show the adjustment required in the journal entry format.
a. Bad debt written off = Opening Balance in bad debt allowance account + Bad debt expense recognized during the period - Closing balance in bad debt allowance account
Bad debt written off = $13,966 + $21,297 - $9,797
Bad debt written off = $25,466
Therefore, the total of accounts written off during the first 11 months is $25,466
b. Date Description and Explanation Debit Credit
31-Dec Allowance for bad debts $347
($9,797 - $9,450)
Bad debt expenses $347
($9,797 - $9,450)
(To record adjustment of allowance of bad debt account)
