The associative property of multiplication states that (a × b) × c= a × (b × c).
(4 x 8) x 3 = (8 x 4) x 3 is an example of the associative property of multiplication.

In step-by-step-explanation
Step-by-step explanation:
2) ( x + 1 ) * ( x - 7 ) = x² - 7x + x - 7 ⇒ x² - 6x - 7
In x² - 6x - 7 a = 1 b = -6 c = -7
3) ( x + 9 ) * ( x + 2 ) = x² + 2x + 9x + 18 ⇒ x² + 11x + 18
In x² + 11x + 18 a = 1 b = 11 c = 18
4) ( x - 5 ) * ( x - 3 ) = x² - 3x - 5x + 15 ⇒ x² - 8x + 15
In x² - 8x + 15 a = 1 b = -8 c = 15
5) ( x + 15 ) * 2 * ( x - 1 ) ⇒ ( x + 15 ) * ( 2x - 2 ) ⇒ 2x² -2x + 30x - 30
2x² + 28x - 30 a = 2 ² b = 28 c = 30
6) ( x - 5 ) * ( 4x - 3 ) ⇒ 4x² - 3x - 20x + 15
In 4x² - 3x - 20x + 15 ⇒ a = 4 b = -20 c = 15
R = 3
6x3=18
18x3=54
54x3=162 ...
Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.
Step-by-step explanation:
For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.
in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.
Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.
Two triangles in sphere that are similar must be congruent.
