Answer:
A. 30
Step-by-step explanation:
The interquartile range for a box and whiskers plot, is the value from the right side of the box minus the value of the left side of the box.
In this case at the far right side of the box it is at 130, at the far left side of the box it is at 100.
130-100=30
 
        
                    
             
        
        
        
3x - 4 = <span>3(-3)  - 4 = -9 - 4 = -13
</span>3x - 4 = <span>3(-1.4)  - 4 = -4.2 - 4 = -8.2
answer
range { -13, -8.2}</span>

Answer:
x=19
Step-by-step explanation:
The perimeter of the right triangle is 
P=9+12+15 =36
The perimeter of the left triangle is 
P =x-7+ x-7+ x-7 = 3x-21
Set them equal
36 = 3x-21
Add 21 to each side
36+21 = 3x-21+21
57 = 3x
Divide each side by 3
57/3 = 3x/3
19 =x
