2x(3x-1) = 6x2-2x because of the distributive property.
Reflexive Postulate, or Identity Postulate.
A postulate is assumed to be true while a theorem is proven to be true. The truth of a theorem will be based on postulates.
A postulate is assumed to be a fact and used to derive conclusions. However, there is no assurance that the postulate is itself true and so all the derived conclusions may depend on a proposition that is not necessarily true. Euclid's fifth, or parallel) postulate in geometry is a notable example.
A postulate is something that is accepted as true without proof. A theorem, on the other hand, is something that has been proven and is now being accepted as true.
Parallel lines are parallel. Proof they have same slopes
Euclid's parallel postulate.
Assuming the question to mean 3*x+3 = 3*(x+1) The reverse, ie 3*(x+1) = 3*x + 3*1 is known as the distributive property of multiplication over addition.
side -angle -side congruence postulate
Could you please specify which postulate you are referring to?
side- side- side congruence postulate
midpoint postulate
Reflexive Postulate, or Identity Postulate.
Yes, it is a similarity postulate.
Side Angle Side postulate.
Yes, it is a similarity postulate.
first five postulate
When a postulate has been proven it becomes a theorem.
