Answer: The number of canned goods in 7th row = 64.
Step-by-step explanation:
The given numbers of canned goods in every row( starting from first ) is represented as
40 , 36, 32, ...
There is a common difference between numbers(d)= 4
∴ Its is an Arithmetic progression.
First term (a) = 40
nth term in A.P. :
7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64
So, the number of canned goods in 7th row = 64.

Answer:
15 sqrt 3.
Step-by-step explanation:
You haven't listed any choices but here's one equivalent:
3 sqrt 75 = 3 * sqrt (3 * 25)
= 3 * sqrt 3 * sqrt 25
= 3 * 5 * sqrt 3
= 15 sqrt 3.
96 = 192 * (1/2) ;
48 = 96 *(1/ 2) ;
24 = 48 *(1/2) ;
. . . . . . . . . .
It'a a geometric sequence with common ratio, r = 1 / 2 .
