The cost of a school lunch is $2.50. Complete the table to show the total cost of 1, 2, 3, and 4 lunche

Step-by-step explanation:

If 1 lunch =$2.50

2 lunches = $5.00 (2.50x2)

3 lunches =$7.50

4 lunches =$10.00

5 lunches= $12.50

basically just add $2.50

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.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
