A company's unadjusted trial balance shows a debit balance in the allowance for doubtful accounts. This means that a. The company has written off more accounts receivable during the period than were accounted for in the opening balance of the allowance. b. The company must recognize bad debt expense at least as great as the unadjusted debit balance of the allowance. c. The company has written off too many accounts receivable and should reassess its write-off policy. d. Both a and b above are correct.

d. Both a and b above are correct.

Explanation:

In the case when the company unadjusted trial balance reflect a debit balance of allowance for doubtful debts so this represent that the company would have more written off account receivable that would be shown in the beginning balance of the allowance. Also the company should record the bad debt expense as more as the debit balance of the non-adjusted allowance  

Hence, the last option is correct

bd = 9 cm

step-by-step explanation:

in a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. that is, the longest side (hypotenuse) is twice the length of the shortest side.

all of the triangles in your geometry are 30°-60°-90° triangles. ac is the hypotenuse of δacd, and the short side of δabc.

the short side ad of δacd will be half the length of ac, so 3 cm. the hypotenuse ab of δabc will be twice the length of ac, so 12 cm. segment bd is the difference of the lengths ab and ad, so is

bd = ab -ad

bd = 12 cm - 3 cm = 9 cm

comment on side length ratios

you can figure the ratios of side lengths in a 30°-60°-90° triangle by considering the trig ratios of the angles. or you can figure the length of the altitude of an equilateral triangle of side length 2 using the pythagorean theorem.
