I will mark you brainliest :) Use Euler's Formula to find the number of vertices in the given polyhedron.

5 faces: 3 rectangles and 2 triangles

There are ? vertices in the polyhedron.

Here's what I've done so far:

There are 3 sides in a trinangle, so 6 sides in total with 12 sides in total for the rectangles, giving me 18... Now what? THANKS!

There are 8 vertices.

Step-by-step explanation:

6 vertices

Step-by-step explanation:

this would make a triangular prism which has 6 vertices

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

17   x 256=4352

sorry if this is wrong, i'm new.
