Solve each seperatly
x+1<-3
minus 1 both sides
x<-4
x-2<0
x<2
so
x<-4 or x<2
graph below
'or' means only one at a time can be true, where they intersect, we can't include those points
so since the solution set x<2 includes x<-4 in it,, the solution set is only -4<x<2
to graph it on a line, see below

Answer:
D
Step-by-step explanation:
The sum to infinity of a geometric sequence is
sum to infinity =
here = 144 and r =
, hence
sum =
=
= = 192 → D
