Algebra II

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

Step-by-step explanation:

Step 1: Define

Identify

Point (1, 5)

Point (-8, 4)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-8-1)^2+(4-5)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(-9)^2+(-1)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{81+1}$
[√Radical] Add: $\displaystyle d = \sqrt{82}$

Solve the following equation (x-4)^2=7

tatyana61 [14]

$(x-4)^2 =7\\\\\implies x-4 = \pm \sqrt 7\\\\\implies x = 4 \pm \sqrt 7\\\\\ \text{Hence,}~ x =4 + \sqrt 7~~ \text{or}~~x =4 -\sqrt 7$
