Answer:
372inches or 31feet
How to:
7feet and three inches is equal to 87 inches and 8ft and 3 inches is equal to 99 inches. Then you know that both sides have to be multiplied by two because there are four sides in the room. Meaning you have 174in and 198in. Then you add those together to get your answer which is 372. To get back to feet just divide by twelve.

Answer:  1) Product property of logarithm,

2) Subtraction property of logarithm

3) Equality property of logarithm

Step-by-step explanation:

By the Product property of logarithm,

log a + log b = log(a.b)

And, By the Subtraction property of logarithm

log a - log b = log(a/b)

Also, by the equality property of logarithm,

log(a) = log(b) ⇒ a = b

Given expression,

log_2(5)+log_2(x+2)-log_2(x+1)=log_2(7)                                                                

\implies log_2(5(x+2))-log_2(x+1))=log_2(7)  (Product property of logarithm)

\implies log_2(\frac{5(x+2)}{2(x+1)})=log_2(7)  (Subtraction property of logarithm)

\implies \frac{5(x+2)}{2(x+1)}=7   ( Equality property of logarithm )

\implies 5(x+2)=7(x+1)    ( Multiplicative property of equality )

\implies 5x+10=7x+7  ( Distributive property of equality )

\implies 3=2x    (subtraction property of equality )

x=\frac{3}{2}       (division property of equality )

7. How does the recognition of revenue on account (accounts receivable) affect the income statement compared to its effect on th
snow_tiger [21]

Answer:

Whenever there is a credit sale, revenue is recognized at the time of sale, and accounts receivables is created, and then revenue increases with the amount of sale, in income statement.

As accounts receivables is increased in indirect method such net increase in accounts receivables from previous year end is deducted under cash flow from operating activities,

Further, recognizing revenue by creating accounts receivable individually does not impact cash flow statement as no cash is affected until amount is collected from accounts receivables.

Thus on a net result, the effect shall be as follows:

Effect on income statement = Increase in income.

Effect on cash flow statement = No effect as does not involve cash
