Postulate

Step-by-step explanation:

A postulate is a statement that is taken as truth, a number of postulates form a theorem which are the basis of mathematics as we know them today, postulates are sentences that are true and make sense, for example, a postulate is:

"If you have a segment "AB" and you draw a point "C" in the segment AB you´ll have that the sum of AC and BC would be equal to the segment AB"

That´s a postulate that is true and is part of a bigger theorem.

for any of you who need the translation here it is

step-by-step explanation:

find the angular size of the equatorial radius of the earth, if the horizontal parallax of the sun

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
