Answer:
The factored equation would be 4x(3y + 7z)
Step-by-step explanation:
In order to find this, look for the greatest common factor and pull it out. Since both have factors of 4 and both have an x, we pull those out. We then divide each term by 4x to get what is left over. 
 
        
                    
             
        
        
        
Answer:
∠4 & ∠8
∠3 & ∠7
Step-by-step explanation:
When the transversal (the line that crosses the other 2) intersects through 2 lines, it forms 2 pairs of alternate interior angles. 
The alternate interior angles are always located in the inner corners of the intersections and are on opposite ends of the transversal.
