Answer:

<u>44 cm</u>

Step-by-step explanation:

<u>Finding Side Length</u>

  • Area = (Side length)²
  • Take the square root on each side
  • Side length = √121
  • Side length = 11 cm

<u>Perimeter</u>

  • A square has 4 sides
  • Therefore, the perimeter is 4 times the side length
  • 4 × 11
  • <u>44 cm</u>

Answer:

  44 cm

Step-by-step explanation:

The area of a square is the square of the side length. This means the side length is the square root of the area.

  s = √A = √(121 cm²) = 11 cm

The perimeter of a square is the sum of its side lengths. There are 4 equal-length sides, so the perimeter is 4 times the length of one side:

  P = 4s = 4(11 cm)

  P = 44 cm

The perimeter of the square is 44 cm.

Solve the inequality 2c/3+1&gt;7
beks73 [17]

Answer:

c > 9

Step-by-step explanation:

(2c/3) + 1 > 7     subtract 1 from both sides

2c/3 > 7 -1

2c/3 > 6  (multiply both sides by 3)

2c > 6(3)

2c>18    (divide both sides by 2)

c > 18 / 2

c > 9

3x - 4y = -15 ; 4x +3y =5
Kipish [7]
Using elimination method to find y
3x - 4y = -15  (multiply 4)
4x + 3y = 5    (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y  = 15
--------------------- - (substract)
         -25y = -75
               y = 3

Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1

The solution (-1,3)
