Answer:
   x = 63°
Step-by-step explanation:
~ They are adjacent angles because they have a common (one) vertex.
~ To find the value of x we must make an equation.
Angles on a straight line add up to 180°.
   117 + x = 180
   x = 180 - 117
   x = <u>63°</u>
 
        
             
        
        
        
        
Answer:
see explanation
Step-by-step explanation:
Given that the the difference of  cubes is
a³ - b³ = (a - b)(a² + ab + b²)
Given
64 - 27 ← a difference of cubes
 - 27 ← a difference of cubes
with a = 4x² and b = 3, thus
= (4x²)³ - 3³
= (4x² - 3)(16 + 12x² + 9) ← in factored form
 + 12x² + 9) ← in factored form
 
        
                    
             
        
        
        
This is solved for all values of 
y = -x-3. (Assuming you meant that 2x+2y=-6).
