4(xsquared -2) thats the answer
Answer:
X=3.5
Step-by-step explanation:
9=x2+2
9-2=x2
(9-2)÷2=x
When you divide a whole number by something, you're asking:
"How many times can I put this thing
into the whole number ?"
If the thing is ' 1 ', then each time you put it into the whole number,
it takes up the space of ' 1 ', and you can do that exactly the same
whole number of times.
If the thing is more than ' 1 ', then each time you stuff it into the
whole number, it takes up the space of more than ' 1 ', so you
can't do that as many times as the whole number.
If the thing is less than ' 1 ', then each time you stuff it into the
whole number, it only takes up the space of less than ' 1 ', so
there'll be enough space in there to let you do that more than
the whole number of times.

Another way to look at it:
When you divide a whole number by something, you're asking:
"How many times can I take this thing away from
the whole number?"
If the thing is ' 1 ', then each time you take it away from the
whole number, you take away exactly ' 1 ', and you can do that
exactly the same number of times as the whole number.
If the thing is more than ' 1 ', then each time you take it away from
the whole number, you take away more than ' 1 ', so you can't do
that as many times as the whole number.
If the thing is less than ' 1 ', then each time you you take it away
from the whole number, you only take away a piece of ' 1 ', so
you can do that more times than the whole number.
Answer:
Total combination = 180,180
Step-by-step explanation:
It is a combination based problem.
So,
Total people = 13
Group = 3,6,2,2
So,
For 6 people
13C6= 1,716
For 3 people
7C3 = 35
For 2 group of 2 people
(4C2)/2 = 3
Total combination = 1,716 × 35 × 3
Total combination = 180,180
