Answer:
is the logarithmic equation which is equivalent to
.
Step-by-step explanation:
According to the laws of logarithms
,where b=base ,n,x all are positive
It can be written in exponential form such as

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

Hence the logarithmic equation for
is
.
Answer:
x = 50
Step-by-step explanation:
add all terms and set sum equal to 360
the 'hint' of (n-2)180 determines how many degrees there are inside the polygon; if 'n' equals the number of sides and the polygon has 4 sides then sum of interior angles is (4-2)180 or 2x180 which is 360
x + 10 + 3x + x + 2x = 360
combine like terms to get: 7x + 10 = 360
7x = 350
x = 50
Answer: 54
Step-by-step explanation: I separated it into 3 areas in my head and then added up 21+21+12 to get 54
7 times 3 is 21
7 times 3 is 21
and
3 times 4 is 12
sorry if i am wrong i just did this in my head
