Answer:
-90%
Step-by-step explanation:
Answer:
the first one is 45% I don't no the second one
Log 3(x²+6x)=log(2x+12). I assume that 3 is a factor of a log with base 10:
if so, then:
log(3x²+18x)=log(2x+12)
==> 3x²+18x=2x+12==> 3x²+16x-12 = 0
solve this quadratic equation & you will find: x'=2/3 & x"=-6
