Find the distance/length of segment AB is A(2.125) and B(98, 15)
balandron [24]

Answer:

146

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Coordinates (x, y)

<u>Algebra II</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

Point A(2, 125)

Point B(98, 15)

<u>Step 2: Identify</u>

A(2, 125) → x₁ = 2, y₁ = 125

B(98, 15) → x₂ = 98, y₂ = 15

<u>Step 3: Find distance </u><em><u>d</u></em>

  1. Substitute in coordinates [Distance Formula]:                                               \displaystyle d = \sqrt{(98-2)^2+(15-125)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                   \displaystyle d = \sqrt{(96)^2+(-110)^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{9216+12100}
  4. [√Radical] Add:                                                                                                 \displaystyle d = \sqrt{21316}
  5. [√Radical] Evaluate:                                                                                         \displaystyle d = 146
