Solution:
Given:
To find f(g(x)):
Therefore, f(g(x)) = 3x + 5
To find g(f(x)):
Therefore, g(f(x)) = 3x + 1
Sum of aritmetic sqeuqnece is
(n/2)(a1+an)
a1=first term
an=nth term
n=how many terms
so we gots
a1=3(1)-4=-1
a18=50
n=18
(18/2)(-1+50)
(9)(49)
441
other one
a1(1-r^(n+1))/(1-r)
2(1-2^(15+1))/(1-(1/4))
about 2 and 2/3, so closer to 3
You can find the perimeter by just counting the distance of every line segment all around the shape since they have vertical and horizontal slopes.
