A polygon has eight sides. a. Name the polygon
b. If two sides of this polygon
are represented by the
expression (2x + 10) and (7x
+ 5), find x.
c. Find the length of each
side of this polygon.

a. octagon

b.  (9x + 15) = 24

c. 24 because all of the sides are equal

Step-by-step explanation:

You add the x values together and the other together to get (9x + 15) which is 24

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

1. perpendicular

2. parallel

3. perpendicular
