26.5 square centimeters

Step-by-step explanation:

You are given two triangle combined and asked to find the area of the figure. The equation to find the area of a triangle is

Area = 1/2 * base * height

where

Triangle 1 has a base=10 cm and a height=3.5 cm

Triangle 2 has a base=6 cm and a height=3 cm

To find the area of triangle 1,

Area = 1/2 * 10 * 3.5 = 17.5 square centimeters

To find the area of triangle 2,

Area = 1/2 * 6 * 3 = 9 square centimeters

So, by adding these two areas we will get the total area of the figure.

Total Area = 17.5 + 9 = 26.5 Square Centimeters

-50/3 is the final answer! : )

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.
