Answer:
The simplified expression is 
Step-by-step explanation:
The given expression is:

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

Divide both the numerator and the denominator by 12b:

The expression finally becomes:

 
        
             
        
        
        
I'd say it is A but I think you have made a tpyo
It should be 2*PI*radius^2 + 2*PI*radius*height

Step-by-step explanation:
We have been given that the elevation of driskill mountain Louisiana is 163 meters above sea level. The death Valley has an elevation of -86 meters.
We can represent this information in an inequality as:  . Our inequality means that the elevation of death valley is less than elevation of driskill mountain.
. Our inequality means that the elevation of death valley is less than elevation of driskill mountain.
