Step-by-step explanation:
= f (8) - f (-5) 
= 3*8-2 -(3*-5-2)
= 22-(-15-2)
= 22+17
= 39
 
        
                    
             
        
        
        
Answer:
200 feet
Step-by-step explanation:
Area of the warehouse 
Let the length of the warehouse=l
The warehouse's width is exactly   of its length
 of its length
Therefore: Width of the warehouse
Area =Length X Width
Therefore:

 
        
             
        
        
        
This is a rectangle, meaning that all angles are right angles and all sides opposite to one another have equal length.
Since the length of CD is 24, the length of AB must also be 24.
Angle B is a right angle because this is a rectangle.
See anything? I'll you a hint. We have a right triangle with only one missing value.
What do we use to solve for missing lengths in a right triangle? The Pythagorean theorem, of course!

The length of c (the hypotenuse) is 26.
The length of a (one leg) is 24.
The length of b is unknown and we want to find it.


Subtract 576 by both sides.

Take square root of both sides.

The length of the missing leg is 10, meaning that the length of BD is 10.
This is what you should be needing. Enjoy!
 
        
        
        
M = 57+46
(Since she has 46 less then martha, you know to find how many martha has you have to add 46!)
M=103
So martha has 103 coins!
