The grid of numbers with a row and column sum of 30 is
3 15 12
17 11 2
10 4 16
<h3>How to prepare the grid?</h3>
The grid in the question has a row sum and column sum of 15
The question implies that we create a similar grid with a row sum and column sum of 30
Represent the grid as follows:
a b c
d e f
g h j
So, we have the following sum of rows
a + b + c = 30
d + e + f = 30
g + h + j = 30
And, we have the following sum of rows
a + d + g = 30
b + e + h = 30
c + f + j = 30
Using trial by error, we have:
3 + 15+ 12 = 30
17 + 11 + 2 = 30
10 + 4 + 16 = 30
When the columns are added, we have
3 + 17 + 10 = 30
15 + 11 + 4 = 30
12 + 2 + 16 = 30
Hence, the grid of numbers is
3 15 12
17 11 2
10 4 16

Answer:
144
Step-by-step explanation:
V=PIr^2h
PI=3
V=3r^2h
r=2 h=12
V=3(2^2)12
V=3(4)12
V=12(12)
V=144in^3
Alright, lets get started.
Two lines are given.
and
If we need to find the intersection point of these two lines, we must solve these two equations and find (x,y) values.
From the first equation,
Adding y in both sides
x = y
We could put this value in second equation
Dividing 11 in both sides
x = -2
So,
y = x means
y = -2
(x,y) = (-2,-2) : Answer
Hope it will help :)
