You would start out with multiplying giving you 5(x+6). then you would have a product of 5x+30. hoped this helped!
        
             
        
        
        
The answer would be 1,500 because 68 is higher than 50 so it will round up to 1,500.
        
             
        
        
        
Answer:
the answer is 64 im 100% sure
 
        
             
        
        
        
M∠A = 42°   [isosceles triangle]
m∠B = 180 - 42 - 42 = 96°  [in a triangle, the three interior angles always add to 180°]
m∠C = 180 - 96 - (x+12)
m∠C = 84 - x - 12
m∠C = 72 - x2x+9 + 3x-1 + 72-x = 180
4x + 80 = 180
4x = 180 - 80
4x = 100
x = 100/4
x = 25m∠C = 72 - x = 72 - 25 = 
47°
