Need to know the answer by december 12th

answer:

step-by-step explanation:

take the last number of the denominator and consider all multiples that result in that number.   if there is a minus sign in front of it, one number will be negative and one will be positive.   if there is a plus sign, either both numbers will be positive or both will be negative.  

after you have the multiples, combine two of them so that the result is the middle number.  

the two numbers are your answers.

hope this ! < 3

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
