Answer:
5
Step-by-step explanation:
(5,3) are the coordinates, so x=5
Give more clarification I don’t understand are the 4 and 16 inches cubic feet meters?
The computation shows that the value of blue which is represented by x is 12.
<h3>How to calculate the value?</h3>
From the information given, it was stated that 30 people were in the kindergarten.
Green = 10
Red = 8
Blue (x) = 30 - (10 + 8)
= 30 - 18
= 12
Since the teacher want to paint the class with the most favorite color, the appropriate color to use will be blue.

If i read this correctly then the answer would be
57-12= 45
45/9= 5
The answer is 5
Let denote the given sequence. has forward differences
{9 - 1, 36 - 9, 100 - 36, ...} = {8, 27, 64, ...} = {2^3, 3^3, 4^3, ...}
If we call the sequence of forward differences , then for ,
is defined in terms of for all by
and so is defined recursively by
We can deduce a pattern for the general -th term:
and so on, up to
We can simplify the right hand side a bit, noticing that matches for :
and to simplify things a bit more, we shift the index of summation:
You should know that the right side has a nice closed form (look up "Faulhaber's formula" if you don't):
