Which polyhedron has more faces than a tetrahedron but fewer faces than an

octahedron?

pentahedron, hexahedron  and heptahedron

Step-by-step explanation:

We have that a polyhedron is a geometric body whose faces are flat and contain a finite volume, depending on the number of faces, its name varies.

Now a tetrahedron has 4 faces and an octahedron has 8, therefore there are 3 polyhedra that fit the description, the following:

pentahedron 5 faces

hexahedron 6  faces

heptahedron  7 faces

Which means that the pentahedron, hexahedron  and heptahedron could be those polyhedron

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
