Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.

Answers

Answer:

52 ft

Step-by-step explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:

Answer:

52m

Step-by-step explanation:

Area of the square floor = 169 m²

For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.

So,

Length of each side of floor = √169 = 13m

For a square with each side 's' , its perimeter will be 4s.

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

Yes, the table does show a function. First, just by seeing that the y values are the same, this means that this is a perfectly horizontal line. Horizontal lines are functions, but vertical lines aren't. I suppose the ordered pairs are just (-2,5), (0,5), and (3,5)

-x - 163 = 12x + 84

Answers

Answer:

X = -19

Step-by-step explanation:

Add x to both sides to get rid of -x

-163 = 13x + 84

subtract 84 from both sides

-247 = 13x

divide by 13

x = -19

X= - 19 always look for that variable

The difference of two numbers is 18. Their sum is 66. What are the numbers? List the numbers from least to greatest.

Answers


attack_panic
·
5y
Another solution is to solve one equation for one variable, and plug that into the other equation.

x + y = 66
x = 66 - y

(66 - y) - y = 18
66 - 2y = 18
-2y = 18 - 66
-2y = -42
-2y/-2 = -42/-2
y = 24

Now that you have y, plug that into the first equation and solve for x.

x + 24 = 66
x = 66 - 24
x = 42

Then plug your two answers into both original equations to verify.

x + y = 66
42 + 24 = 66
66 = 66 check

x - y = 18
42 - 24 = 18
18 = 18 check

Answers

Answer:

Sorry, I tried.

Hope this helps.

Step-by-step explanation:

The chosen topic is not meant for use with this type of problem. Try the examples below.

6x2+3y2=126x2+3y2=12 , x+y=2x+y=2

x+2y=4x+2y=4 , x−y=−3x-y=-3

x2−y=2x2-y=2 , 2x−y=−12x-y=-1

Y:
-5y + 87 = -18
-5y = -18 - 87
-5y = -180
y = -180 / -5
y = +36

X:
( 5 x 36 ) + 2x = 58

180 + 2x = 58

2x = 58 - 180

2x = -122

x = -122 / 2

x = -61
