h = 4(x+3y) + 2
4×x = 4x
4×3y= 12y
4x+12y+2
x=
tell me if im wrong
ignore the last bit, x=$

We have that
<span> |x+6| >= 5
step 1
resolve for (x+6)>=5------> x>=5-6-------> x>= -1
the solution is the interval </span>(-1, ∞)
<span>
step 2
resolve for -(x+6) >=5------> -x-6 >=5----> -x >= 5+6---> -x>=11----> x<=-11
</span>the solution is the interval (-∞, -11)
<span>
using a graph tool
see the attached figure
the solution is the interval (-</span>∞, -11) ∩ (-1, ∞)
