Which expressions are equivalent to the one below ? check all that apply. log3 3+ log3 27

Step-by-step explanation:

We know logrithms addition is equivalent to log of multiplication.

i.e. log a + log b = log ab if bases are equal

Here given expressions are log 3 and log 27 with same base 3.

Hence log  3+log 27 = log 3(27) = log 81

81 can be written as 3 power 4

So given expresssion

=

(By log rules that

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
