How you prove that -if r is rational and x is irrational then prove that r x and rx are rational?
You cannot, because the statements are false! (The second is rational only if r = 0).
What did Copernicus prove to mankind?
Copernicus proved to mankind that the sun was the center of the universe, not the Earth. We know now that he was mostly correct. The sun is the center of the solar system.
Describe the methods to prove that a quadrilateral is a rectangle?
you can prove any one of these statements to prove that quadrilateral is a rectangle: -- Opposite sides are parallel and any one angle is a right angle. -- Opposite sides are equal and any one angle is a right angle. -- All four angles are right angles. -- Adjacent angles are complementary, and one of them is a right angle. -- Opposite sides are either equal or parallel, and area is equal to the product of two adjacent sides. -- Diagonals are equal.
What are the proofs that a quadrilateral ia s parallelogram?
There are 5 ways to prove a Quadrilateral is a Parallelogram. -Prove both pairs of opposite sides congruent -Prove both pairs of opposite sides parallel -Prove one pair of opposite sides both congruent and parallel -Prove both pairs of opposite angles are congruent -Prove that the diagonals bisect each other
How can properties be used to prove rules for multiplying integers?
The answer depends on which properties are being used to prove which rules.

Did Copernicus prove that the sun is the center of the universe?

You cannot, because the statements are false! (The second is rational only if r = 0).

Why do you think that Wegener was unable to prove the theories of continental drift and plate tectonics before his death in 1930?

What is used to the steps of a geometric proof?
we use various theorems and laws to prove certain geometric statements are true
Is mathematics based on assumptions?
In a way, yes. Certain "postulates" or "axioms" are assumed to be true; all other statements are derived from those. The "postulates" are chosen so that they are reasonable and simple assumptions.If you try to prove the postulates, you have to derive them from some other statements, so sooner or later, you will always have unproved statements. That can't be avoided.In a way, yes. Certain "postulates" or "axioms" are assumed to be true; all other statements are derived from those.
