345 ft squared

Step-by-step explanation:

You can split the polygon into two rectangles. The first rectangle has a length of 25 and a height of 11 which makes an area of 275. The second rectangle has a length of 10 and a height of 7 which makes an area of 70. Then you add these two areas together and you get 345.

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.

the answer is c. 23/3
