Answer:
the answer is 3x-5
Step-by-step explanation:
break the expression in to groups
3x^2 + 4x -15 = (3x^2 -5x) + (9x-15)
factor out x from 3x^2 -5x: x(3x-5)
factor out 3 from 9x-15: 3(3x-5)
=x(3x-5) +3(3x-5)
factor out common terms
(x+3) (3x-5)
=((x+3) (3x-5)) / (x+3)
cancel the common factor x+3
=3x-5
Answer:
-0.6309
Step-by-step explanation:
Using the change of base formula,
Log 1/2 to base 3 = Log1/2 ÷ Log 3 = Log 0.5 ÷ Log 3
Log 0.5 = -0.3010
Log3 = 0.4771
Log 0.5 ÷ Log 3 = -0.3010 ÷ 0.4771 = -0.6309
