Describe the shape below. A 7-sided (heptagon) concave polygon.
A 6-sided (hexagon) convex polygon.
A 5-sided (pentagon) simple polygon.

7-sided concave polygon

Step-by-step explanation:

count the sides and also it's concaved, lol

A 7-sided (heptagon) concave polygon.

Step-by-step explanation:

That is a Heptagon, and it is concave, which means it caves inwards.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
