Answer:
-19
Step-by-step explanation:
It is a non repeating decimal
Answer: Line DB
Think of the two planes as pages in a book. They are joined by the spine, which is where the two planes intersect. In this case, that intersection is the line DB.
Point D is on both planes R and S. So is point B. Every point on line DB is found on both planes.
N= 3a - 8
______
a-b
- First you will use the distributive property for multiplication on the left side of the equation.
- Combine like terms and change the signs
- Isolate n by factoring
- Divide both sides of the equation by a-b

Answer: SSS Postulate</h3>
The tickmarks tell us which pairs of sides are the same length.
- AB = BC due to the single tickmarks
- AD = CD due to the double tickmarks
So far we have two pairs of congruent sides.
The third pair of congruent sides are the overlapping or shared sides BD = BD which is true by the reflexive property (anything is congruent to itself).
Overall we have three pairs of congruent sides allowing us to use SSS. Each "S" stands for "Side".
