Solve each equation by completing the square

n2 + 4n - 12 - 0

Step-by-step explanation:

We begin with the equation

When we complete the square, we work off the the second coefficient. In this case, it is 4.

The first thing we must do is half this number

This gives us 2.

Then we have to square it, which gives us 4.

We then can add and subtract this number from this equation

This doesn't look like much, but we can now group these terms together and then solve the problem.

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
