True or false the edges of a polyhedron are the line segments bordering each face?

The given statement " the edges of a polyhedron are the line segments bordering each face" is true.

Step-by-step explanation:

A polyhedron is a 3 D solid figure possessing straight edges and flat sides. The flat sides are called the faces and the corners are called vertices. The edges of a polyhedron are the lines at folds, where these faces meet each other. The two faces are joined, it joins in a line.

Therefore, the given statement is true.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
