The area of a rectangular pool can be modeled as 5(x+7) if the area of the pool is 85 square feet, what is the value of x
Marina86 [1]
We have:

5(x + 7) = 85    |divide both sides by 5

x + 7 = 17    |subtract 7 from both sides

x = 10

<u>Geometry</u>

Radius of a Circle Formula: r = d/2

  • r is radius
  • d is diameter

Area of a Circle Formula: A = πr²

Step-by-step explanation:

<u>Step 1: Define</u>

Diameter <em>d</em> = 18 units

<u>Step 2: Manipulate Variables</u>

Radius <em>r</em> = 18 units/2 = 9 units

<u>Step 3: Find Area</u>

  1. Substitute in <em>r</em> [Area of a Circle Formula]:                                                       A = π(9 units)²
  2. [Area] Evaluate exponents:                                                                              A = π(81 units²)
  3. [Area] Multiply:                                                                                                  A = 81π units²
