Answer:
Any value of x
<em></em>
Step-by-step explanation:
Given


Required
What value of x is 
Solving for f(g(x))


Solve the inner square



Solving g(f(x))





Equate f(g(x)) and g(f(x))


<em>This implies that </em>
<em> at any value of x</em>
411 is the total amount of shells he would use
Step-by-step explanation:
LO is a straight line,
Therefore, m<NML +m<NMO = 180°
z+ x+20=180°
z= 180°-x-20°
z= 160°-x
m<KNM+m<NML=180°. (co-interior angles)
2x-60+z=180°
2x-60+160°-x=180°
x+100°=180°
x=80°
m<NKL+m<KLM=180°(co-interior angles)
2y+y=180°
3y=180°
y=60°
z=160°-80° =80°
