Answer:
ln (m^2n^9)
Step-by-step explanation:
Rule: ln a + ln b = ln ab
Rule: ln a^n = n * ln a
2 ln m + 9 ln n =
= ln m^2 + ln n^9
= ln (m^2n^9)

<span>-8 < x -3 < 1
we have two inequations: 
* -8<x-3 and -8+3<x-3+3 or -5 < x or x>-5
*  x-3<1 or x-3+3<1+3 and we have x<4
For all cases we have -5<x<4
or </span><span>interval notations: x</span>∈(-5;4)

Answer:
238 miles
Step-by-step explanation:
340 miles = 5 hours 
So get 1 hour by dividing by 5 on both sides 
5/5 = 1 hr
340/5 = 68 
So in 1 hour they travel 68 miles
You want to find 3 1/2 hours 
Do 68 x 3 to get 3 hours 
So it would be 68 x 3 =204
Plus the half an hour - which you get by doing 68/2 = 34 
<em>68 = 1 hour, so half of that must be half an hour</em> 
So to get the final distance you do 204 (3 hours) +34 (half an hour) 
204 + 34 =238
