Step-by-step explanation:
The geometric terms modelled will be:
1. Plane
2 Point
3Point
4Plane
5Line
6.Point
7Point
8 Plane
9.Plane
10.Line
<h3>What is a line?</h3>
It should be noted that a line is a one-dimensional figure, that has length but no width. It should be noted that a line is made of a set of points that is extended in opposite directions.
The plane is flat surface.

Name the geometric term modeled by each object.
1. wall of a classroom
2. a knot in a piece of thread
3. tip of a needle
4 floor of a room
5 edge of a table
6. tip of a pencil
7 far distant star
8 screen of a flat TV
9 sheet of paper
10. light beam
Answer:

Step-by-step explanation:
Factorise the numerator and denominator
8a² - 2 ← factor out 2 from each term
= 2(4a² - 1) ← 4a² - 1 is a difference of squares
= 2(2a - 1)(2a + 1)
4a² + 4a + 1 ← is a perfect square
= (2a + 1)²
Thus

=
← cancel (2a + 1) on numerator/ denominator
= 
= 
That is true because factors of 40 are 10,5
the question in English
Juan has blue cubes with a 55 mm edge and red cubes with a 45 mm edge. He stacks them in two columns, one of each color; he wants the two columns to be the same height. How many cubes does he need, as a minimum, of each color?
Let
x---------> the number of blue cubes
y--------> the number of red cubes
we know that
Juan wants that the two columns to be the same height
so

solve for y

I proceed to calculate a table, assuming values of x to calculate the value of y. When the values of x and y are whole numbers, I will have found the solution.
the table in the attached figure
therefore
<u>the answer is</u>
9 blue cubes
11 red cubes
