the awnser would be a(g(x)=3x2 
 
        
             
        
        
        
U need to simplify 5×5 to 25,move the negative to the left, then simplify the brackets
        
             
        
        
        
-3w= -7w-7 =
-3w+7w = -7w+7w - 7 =
4w= -7
4w/4 = -7/4 =
w = -7/4
        
             
        
        
        
Answer:
Step-by-step explanation:
Each child received two pieces.
So total   pieces received by 4 children = 4*2 = 8
Total pieces = 10 + 8 = 18
 
        
                    
             
        
        
        
(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
 4x + 1 = 2x + 5
 4(3) + 1 = 2(3) + 5
 12 + 1 = 15 + 5
 13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
 4x - 2x = 5 - 1
 2x = 4
 x = 4/2
 x = 2
This shows that x = 2 makes the equation true.
