We have that
<span>y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2
we know that
</span>If two lines are parallel<span>, then they will never intersect
</span><span>
therefore
the answer is the option

I don't know about the first one but for the second one:

Answer:
84 feet
Step-by-step explanation:
-16(1.5)^2+120=84
first polygon
ext. angle=180°-120°
=60°

n=360°/60°
n=6
second polygon
n=2(6)=12
ext. ang= 360°/n = 360°/12° = 30°
int. ang = 180°-30°= 150°
answer is C
