Which expression is equivalent to log 20 + 2 log x - log y ? a) log(20x^2y) b) log(10x/y) c) log(20/x^2 y) d) log(20x^2 /y)​

OPTION D

log(20x²/y)

is the correct answer

the answer is D!

Step-by-step explanation:

have a nice day!!!

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
