Answer:
2<∛13<3      1<∛6<2
Step-by-step explanation:
Lets find the integers a and b  ∛13 lies between.
a<∛13<b
a³<13<b³
=> a=2 so 2³=8   and b=3 so 3³=27    8<13<27
Similarly     a<∛6<b
a³<6<b³
a=1    and b=2
 
        
             
        
        
        
Answer:
x={(y+1) / 5}²
Step-by-step explanation:
y = 5√x +3 -4
⇒y = 5√x -1
add 1 on both sides
⇒ y + 1 = 5√x 
divide both sides by 5
⇒(y+1) / 5   = (5√x) /5
⇒(y+1) / 5   = √x
now, square both sides
⇒{(y+1) / 5}²  = (√x)²
∴{(y+1) / 5}² = x
 
        
             
        
        
        
Answer:
7x+54
Step-by-step explanation:
because you distribute the 7 to the x and the 8 first then you bring that down which becomes 7x+56 then you to the addition so you do 56+-2 which would give you 54. 
 
        
             
        
        
        
Answer:
3(2x-5)+4(x+2)
=33
Step-by-step explanation:
3(2x-5)+4(x+2)
3(2(4)-5)+4(4+2)
3(8-5)+4(6)
3(3)+24
9+24
33
