This forms a right angle triangle with sides of: x, 2x+4, and 2x+6 (your hypotnuse)

a^2 + b^2 = c^2

so sub in:
x^2 + (2x+4)^2 = (2x+6)^2
x^2 + (4x^2+16x+16) = 4x^2 +24x+36
5x^2 + 16x +16 = 4x^2 + 24x + 36
x^2 – 8x – 20 = 0
(x-10) (x+2) = 0
x = 10, -2

but -2 means you’re taking steps backwards…so we discard that answer and just use 10.
sub in and solve:

2x+6 = 2(10)+6 = 26 pace from Castle Rock.
good luck
