Answer:
d=252m, u dint put the speed it was rolling at from point B to C so I could only solve for A to B. However if you use the formula below you can find the distance from B to C and add that to A to B giving the total distance rolled.
Step-by-step explanation:
d=vt
v=14m/s
t=18s
d= vt, (14m/s)(18s)
d=252m
 
        
                    
             
        
        
        
So 5,10,15,20,25,30,35,40,45 so Aylson needs 1 more bead. Because 45 beads are already used!

Answer:
7(x)=5x+7
to find the x / zero intercept, plug in f (x) = 0 
0=5x+7
move the left side and change the sign 
-5x7
divide both of the equation by -5
x= 
same steps for g(x)=-2x-4
x=-2
