Answer:
3 cm
Step-by-step explanation:
Set up an equation that solves for the surface area, "112 " :
" :
10(2)+10(2)+2x+2x+10x+10x = 112
20+20+4x+20x = 112
24x+40=112
24x=72
x=3
So, 3 cm.

Answer:
>.
Step-by-step explanation:
93/100 = 0.93
2/5 = 0.4,  so:
93/100 > 2/5.
 
        
             
        
        
        
Answer:
B. 8x^2-6x-7
Step-by-step explanation:
All you have to do is combine the like terms. 
Like terms are the terms that have the same variable and same exponent.
The like terms in this equation are 6x^2 and 2x^2, 11x and -17x, and -3 and -4.
When you add 6x^2 and 2x^2, you get 8x^2
When you add 11x and -17x, you get -6x
When you add -3 and -4, you get -7.
Putting these all in order, your answer is 
8x^2 - 6x - 7
 
        
             
        
        
        
So if 18 + x =43, then what you need to do is 
 18 + x =43
-18 -18
——————
 x = 25
because whatever you do to one side, you need to do to the other
