Square with sides measuring 12 in. What is the perimeter and area?

2 answers:

48 is the perimeter, all sides in a square are equal, you take 12 * 4 which gives you 48.

For the area, you take two sides, length and width, and you multiply them, 12 * 12, this gives you 144.

Well a square has 2 dimensions (used for area) and 4 sides (used for perimeter). Perimeter is the measure of the total outside length of a shape, and since there are 4 sides on a square and each side of the square is 12 inches long, the perimeter can be found by multiplying the length of each side by the number of sides (12 x 4 = 48).
P = 48 inches
Area is the measure of the square units taken up by the shapes interior, so you multiply the lengths of the two dimensions in a square by each other to find the area (12 x 12 =144).
A = 144 inches^2

Answer:

Step-by-step explanation:

(3x -14) + 9x is 90 degrees, so if you add 90 it becomes 180 degrees

It is 90 degrees because you can see that there is a right angle there

Given the function f(x) = 2x+4 and the domain: {-1,0,1},determine the range

Svetlanka [38]

Answer:

f(x) = 2x + 4 domains {-1, 0, 1}

range {2, 4, 6}

(please mark brain if this helps and is correct)

Step-by-step explanation:

to solve f(x) to find the range you would want to input all the domain numbers in the equation f(x) to get the range of all the numbers you need

step 1: take the first domain number and input it into your equation where x is

ex: 2x + 4 [2(-1) + 4] = -2 + 4 = 2

step 2: add the second domain number and input it into your equation where x is

ex: 2x + 4 [2(0) + 4] = 0 + 4 = 4

step 3: add the last domain number and input it into your equation where x is

ex: 2x + 4 [2(1) + 4] = 2 + 4 = 6

Now we have determined what the range is

In how many ways could 12 people be

laila [671]

Step-by-step explanation:

There are total 12 People

Person 1, Person 2,3,4,5,6,7, 9, 10, 11 and 12 at a round table

12 Chairs: 1,2,3,4,5,6,7,8,9,10,11 and 12

Let chairs 1 and 2 be next to each other

Person 1 is at chair 1 and Person 2 is at chair 2

The rest of the people on 3,4,5,6,7,8,9,10,11 and 12 - can sit in 10! ways

Next, Person 1 and Person 2 change their positions;

Person 1 is sitting at 2 and Person 2 is sitting at 1

The rest of the people on 3,4,5,6,7,8,9,10,11 and 12 - can be rearranged in 10! ways

Therefore, total number of ways in which Person 1 and Person 2 are next to each other is: 2*10! = 7257600

As we then have to find in how many ways they are not sitting next to each other; subtract 7257600 from the total number of possible arrangements.

In circular permutation,

Total number of arrangements of n people = (n-1)!

Here the number of people is 12

Arrangement = (12-1)! = 11!= 39916800

Therefore, the number of ways Person 1 and Person 2 are not next to each other = 39916800 - 7257600 = 2659200
