Cones aren't constructed from polygons so it would be the first one

Answer: Cone

Step-by-step explanation:

A polygon is any 2-dimensional shape which is formed with straight lines. Fr example : quadrilateral, triangle etc.

1) A cone is a three-dimensional geometric shape that has a circular base,

And, circular base is not a polygon, that's why it is not constructed completely from polygon.

2) An Octahedron is a polyhedron with eight faces, twelve edges, and six vertices and it can be formed by polygons.

3) A prism is also a polyhedron having two parallel faces which are called bases. In which, The other faces are always parallelograms.

It is always formed by polygons.

4) A pyramid is a polyhedron that has a base that can be any polygon, and three or more than three triangular faces which meet at a point.

Can someone finish the whole thing ??

Romashka-Z-Leto [24]

<h3>Answer: y = (3/2)x + 0</h3>

This is the same as y = (3/2)x

=============================================================

Work Shown:

Find the slope of the line through (x1,y1) = (-2,-3) and (x2,y2) = (2,3)

m = (y2 - y1)/(x2 - x1)

m = (3 - (-3))/(2 - (-2))

m = (3 + 3)/(2 + 2)

m = 6/4

m = 3/2

The slope is the fraction 3/2. This is going to be in front of the x, or to the left of the x.

----------

Plug m = 3/2 and (x1,y1) = (-2,-3) into the point slope formula. Solve for y.

y - y1 = m(x - x1)

y - (-3) = (3/2)(x - (-2))

y + 3 = (3/2)(x + 2)

y + 3 = (3/2)x + (3/2)(2)

y + 3 = (3/2)*x + 3

y + 3 - 3 = (3/2)*x + 3 - 3

y = (3/2)x + 0

The y intercept is zero. This matches up with the fact the graph crosses the y axis at y = 0.

Select all line segment measurements below that could NOT be used to form a triangle. a triangle with the side measurements of 3

lara31 [8.8K]

Answer:

a triangle with the side measurements of 2, 3, and 5 inches

a triangle with the side measurements of 7, 8, and 16 inches

a triangle with the side measurements of 4, 4, and 8 inches

Step-by-step explanation:

A triangle is a polygon shape with three sides and three angles. There are different types of triangles such as isosceles triangle, scalene triangle, equilateral triangle and right angle triangle.

The triangle inequality theorem states that the sum of any two sides of a triangle is always greater than the third side.

For a triangle with the side measurements of 3, 4, and 6 inches:

3 + 4 > 6. This can be a triangle

For a triangle with the side measurements of 2, 3, and 5 inches:

2 + 3 is not greater than 5, hence it cannot be a triangle

For a triangle with the side measurements of 3, 3, and 4 inches:

3 + 3 > 4. This can be a triangle

For a triangle with the side measurements of 5, 5, and 5 inches

5 + 5 > 5. This can be a triangle

For a triangle with the side measurements of 4, 4, and 8 inches:

4 + 4 is not greater than 8, hence it cannot be a triangle

For a triangle with the side measurements of 7, 8, and 16 inches:

7 + 8 is not greater than 16, hence it cannot be a triangle
