Hello,
x^3+64=0
==>(x+4)(x²-4x+16)=0
==>x=-4 because x²-4x+16 is not factorable in R.
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

I don’t know but I’m going to say that the answer is 48? I don’t know. If I’m wrong please help me understand this. Lol this is the same thing I’m doing right now and the question I was actually about to ask
Answer:
The volume of new sphere is 3.375 times greater than the volume of old sphere
Step-by-step explanation:
Let r be the radius of old sphere. This old sphere is dilated by a scale factor of 1.5 to create a new sphere, so the radius of new sphere is R=1.5r.
The volume of the sphere can be calculated using formula
Hence,
