Answer:  2

<u>Step-by-step explanation:</u>

3 ln (2) + ln (8) = 2 ln (4x)

  ln (2)³ + ln (8) =   ln (4x)²

  ln (2³ · 8)        =   ln (4x)²

      (2³ · 8)        =      (4x)²    

           64         =      16x²

            4          =          x²

           ±2        =           x

-2 is an extraneous solution because x > 0

The only valid answer is x = 2

Shift the graph of f left 7 units. 

Ignoring everything but what is with the x (x-2) and (x+5)

-2 inside the parentheses is right 2 on the graph 
+5 inside the parentheses is left 5 on the graph

so if you want to make f look like g then you have to bring it left 7

Answer:

Speed = Distance/time in km/h

a) 18 feet in 20 minutes

0.0054864 km/0.333333hours

=0.01645921645 km/h

b) 90 feet in 2.5 hours

0.027432km/2.5

=0.0109728 km/h

c) 20 yards in 1.5 hours

0.018288km/1.5

=0.012192 km/h

d) 3 2/3 yards in 15 minutes

0.003352800000003048km/0.25hours

=0.0134112

So I think its safe to say that A is the fastest in comparison
