Its 3. Because 5*3 is 15 and 9*3 is 27
Answer:
D = 13 units
Step-by-step explanation:
<u><em>Using Distance Formula to find the length.</em></u>
Distance Formula = 
D = 
D = 
D = 
D = 
D = 13 units
Comment
The only way I can envision this is put all 4 points on 1 line segment. They go in the order of ADCB. I can only draw it this one way.
Given
D is the midpoint of AC
C is the midpoint of DB
AC = 3 cm
Argument
AC = 3 cm Given
AD = DC D is the midpoint of AC
AD = 3/2 Definition of a midpoint.
DC = 3/2 Definition of a midpoint
DC = 3/2 Last statement
DC + CB = 1.5 + 1.5. C is the midpoint of BD
DB = 3 Consolidation of equals
AD + DB = AB
1.5 + 3 = 4.5 Substitution.
Answer:
I think the answer is C if I'm wrong sorry its been two years since i last learnt this
Step-by-step explanation:
Answer:
C. The statement is false. Geometry is an axiomatic system where the accepted principles are the undefined terms point, line and plane.
Step-by-step explanation:
The 4 basic characteristics of axiomatic systems are:
- Undefined terms (or primitive terms)
- Axioms (or postulates)
- Theorems
- Laws of logic
The undefined terms or primitive terms of geometry are points, lines and planes that at some point meet or join together. This is called incidence, since geometry studies their relationship. E.g. 3 lines that form a triangle on a plane.
