Answer:
d = 
Step-by-step explanation:
Given
= 16(d + 1) = - 20 ← distribute parenthesis on left side
- 16d - 16 = - 20 ( add 16 to both sides )
- 16d = - 4 ( divide both sides by - 16 )
d = 
=
Any number that is irrational, such as
0.4 + pi because pi is an irrational number.
Answer:
See below.
Step-by-step explanation:
Draw segment OB.
In triangle OBC, points R and S are the midpoints of sides OC and BC, respectively. That makes RS parallel to OB.
In triangle OBA, points P and Q are the midpoints of sides OA and BA, respectively. That makes PQ parallel to OB.
Since segments RS and PQ are parallel to segment OB, then RS and PQ are parallel to each other.
