Answer:
49x^2 - 28x + 4 
Step-by-step explanation:
(7x - 2)(7x - 2)
Because squares have the same length of sides. 
49x^2 - 28x + 4 
 
        
             
        
        
        
Answer:
 y = -7 
Step-by-step explanation:
Put x = 2 in any one of the equation
5x +2y = -4
5*2 + 2y = -4
10 +2y = -4
       2y = -4 -10
       2y = -14
         y = -14/2
          y = -7

Answer:
4x=90
X=90÷4
X=22.5
5x-27=90
5x=90+27
5x=117
X=117÷5
X=23.4
So 23.4 is a larger angle
