Why do you disregard the negative square root in the pythagorean theorem? 25     !

The pythagorean theorem is

However, r is defined to be a distance, which has no meaning when it is negative.

[edit] Since negative distance has no meaning, the negative square root in above equation is never used.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

i pretty sure it is
