40xa^2 + 24 ax + 32 a = 
all you have to do is factor out a 8a from each term 
aka reverse distribution property 
8a (5 a + 3x + 4)
        
             
        
        
        
Answer: y = 2x +2 
You need to first pick two points from the graph. Then you need to find the slope and plug in one of the original points you used to find the slope into the slope-intercept formula in order to find the b - intercept.

Answer:
all three angles should add up to 180 so subtract what you know from 180 and you should be able to find everything from there
 
        
             
        
        
        
recall that a circle has a total of 360°.
so that missing central angle is then 360° - 110° - 65° - 90°. Well, the arc's angle measurement is the same as the central angle they're in, so the x° is the same as 360° - 110° - 65° - 90°.
