Answer:
Perimeter = 12ft
Step-by-step explanation:
Given that the distance between the table and each corner of the table setting is 2feets it implies the table settings is place at the center of each table.
Since the table settings is at the center of the table and each table settings are 3feets apart, it implies that distance from table setting to the end of the table will be 3ft/2 = 1.5ft
If half length of the table is 1.5ft
Length = 2 x 1.5ft = 3ft
Formular for perimeter of a square = 4L
Perimeter = 4 x 3 = 12ft

Answer:
88
Step-by-step explanation:
We are given that in arithmetic sequence , the nth term is given by the formula
Where
d=Common difference
In an geometric sequence, the nth term is given by
Where r= Common ratio
1,4,7,10,..
We have to find 30th term.
Therefore, given sequence is an arithmetic sequence because the difference between consecutive terms is constant.
Substitute n=30 , d=3 a=1 in the given formula of arithmetic sequence
Then, we get
Hence, the 30th term of sequence is 88.
