Answer:
   C
Step-by-step explanation:
The step shown indicates that y was eliminated from the equations. For choices A, B, D, this is done by adding the equations together (the y-coefficients are opposites). The result of doing that gives x-terms of 4x, 0x, and 0x, respectively. These x-terms do not match the one given: 2x.
For choice C, the y-term is eliminated by subtracting twice the second equation from the first. Doing that gives ...
   (4x +2y) -2(x +y) = (14) -2(3)
   4x +2y -2x -2y = 14 -6 . . . . eliminate parentheses
   2x = 8 . . . . . . . . . . . . . . collect terms
 
        
             
        
        
        
Answer:
52°
Step-by-step explanation:
<D = 360 - (78+106 + 124)
<D = 360 - 308
<D = 52°
 
        
                    
             
        
        
        
Step-by-step explanation:
Factor, in mathmatechis, a number or algebric expression that divides another number or expression evenly.
For example, 3 and 6 are factors of 12 because 12 divided by 3 equals 4 exactly and 12 divided by 6 equals 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
