Answer:
320x^2+140x-10
Step-by-step explanation:
(16x-1)(20x+10)
320x^2+160x-20x-10
320x^2+140x-10
 
        
             
        
        
        
Answer:
<h2>        
 X-intercept: (2, 0)
</h2><h2>
         Y-intercept: (0, 6)
</h2>
Step-by-step explanation:
X-intercept means y-coordinate of 0:
6x +2×0 = 12
 6x = 12
   x = 2         ← x-coordinate
Y-intercept means x-coordinate of 0:
6×0 + 2y = 12
 2y = 12
   y = 6         ← y-coordinate
 
        
             
        
        
        
Using the triangle inequality theorem, we can figure this out.
2-  Yes
3- No
