X = (12 +- sqrt (144 -4(7)(3))/14
x = (12 + - sqrt (144 - 84))/14
x = (12 + - sqrt(60))/14
x = (12 + - 2sqrt 15))/14
x = (6 + - sqrt 15) / 7

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

Step-by-step explanation:

Step 1: Define

Point (-1, -13)

Point (-1, 21)

Step 2: Find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-1+1)^2+(21+13)^2}$
(Parenthesis) Add: $\displaystyle d = \sqrt{(0)^2+(34)^2}$
[√Radical] Simplify: $\displaystyle d = \sqrt{(34)^2}$
[√Radical] Evaluate: $\displaystyle d = 34$
