Answer:
arrange them: -9x^3+2x^3-4x^2+x^2-6x-5x
the simplified is: -7x^3-3x^2-11x
The <em><u>correct answer</u></em> is:
A line of reflection would need to be drawn as a line that bisects a vertex angle of the pentagon.
Explanation:
A line that bisects a vertex angle of a pentagon will be a line of symmetry within the pentagon. The pentagon can be "folded" through this line into two equal halves.
This imaginary line represents the center of the pentagon. A reflection through this line will carry the pentagon onto itself. This is due to the definition of line symmetry:
"A set of points has line symmetry if and only if there is a line, l, such that the reflection through l of each point in the set is also a point in the set."
Additionally, for any regular polygon, the number of lines of symmetry equals the number of sides.
This means that this line can be through any vertex angle of the polygon.
To find the lateral surface area of a pyramid, you can find the area of each triangle, A = 1/2bh or A = 1/2lw, then multiply by the number of triangles, which would be based on the number of sides of the base; or you can take half the perimeter and multiply by the slant height.
