Answer: n=15

Step-by-step explanation:

To find the perimeter, you add all of the side lengths together. This would make the equation 28+28+n+n. You already know the perimeter and are trying to find n. Your new equation is 28+28+n+n=86

You would then combine the like terms and get

56+2n=86

Then you would subtract 56 from both sides and get

2n=30

Finally, you want to divide both sides by 2 in order to get n alone. 30/2 is 15. Therefore,

N=15

To arrange numbers from least to greatest:

First write them down in decimal form. Now it will be easy to determine which value is greater than the other.

Arrange the decimal numbers from least to greatest.

Finally revert the decimal values to their fraction form having arranged them from one with least value to one with greatest value.

23 + 8m + 4n - 5m - 27

mylen [45]

Answer:

$-4 + 3m + 4n$

Step-by-step explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

So we should start on the number without variables:

23 and 27

Match them up together and you should find your first equation:

23 - 7

==> -4

So we should have -4 + 8m + 4n - 5m

Now we should combine the numbers with the variable of m:

8m and 5m

Match them up together and you should find your first equation:

8m - 5m

==> 3m

So we should now have -4 + 3m + 4n

Since there are no other variables of n, we are all done:

-4 + 3m + 4n is your final answer

A= 30ft, because you only have to multiply LxW= A that is equal to 2x15=30ft
