Answer:

100+20π

Step-by-step explanation:

Find the diagram attached.

Perimeter of a square =4L

L is the side length of a square

From the diagram;

L = 10

Perimeter of a square = 4(10) = 40

Perimeter of 3 squares = 3(40) = 120

2 semi circle = a circle

Perimeter of a circle= 2πr

radius of the Circle = length of a side of the square.

Area of the circle = 2π(10)= 20π

Perimeter of the shape = Perimeter of the two semicircle + area of the 4squares = 100+20π

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

<u>Algebra I</u>

  • Standard Form: ax² + bx + c = 0
  • Factoring
  • Multiple Roots
  • Completing the Square: -b/(2a)

Step-by-step explanation:

<u>Step 1: Define</u>

2x² - 20x = x² - 19

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. [Subtraction Property of Equality] Subtract x² on both sides:                     x² - 20x = -19
  2. Complete the Square [Addition Property of Equality]:                                 x² - 20x + 100 = -19 + 100
  3. [Complete the Square] Simplify:                                                                    (x - 10)² = 81
  4. [Equality Property] Square root both sides:                                                  x - 10 = ±9
  5. [Addition Property of Equality] Add 10 on both sides:                                 x = 10 ± 9
  6. Evaluate:                                                                                                          x = -1, 19
