Answer:
Step-by-step explanation:
- find the area of the base (square)=900 sq. cm 
- find area of triangles=1260 sq. cm
- total= 2160 sq. cm
 
        
             
        
        
        
2x-1=5
2(3)-1=5
6-1=5
5=5 
x=3
        
                    
             
        
        
        
Answer:
10 < x < 20
Step-by-step explanation:
the sum of any two sides of a triangle has to be greater than the 3rd side, so the maximum value of the third side in this instance is 19.9999999 because 10 + 10 = 20
 
        
             
        
        
        
<span>8 - 1/3x = 16
</span>⇒ -1/3x= 16-8
⇒ -1/3x= 8
⇒ x= -24
The final answer is -24~
        
             
        
        
        
Answer:

Step-by-step explanation:
The multiplicative inverse of a number n is 
The product of the number and its multiplicative inverse = 1
n ×  = 1
 = 1
Thus the multiplicative inverse of  is
 is
 =
 =
