Ared string of holiday lights blinks every 3 seconds while a string of blue lights blink every 4 seconds

I don't know if you had a question to ask, or if you're just giving us
some interesting information about holiday lights. 

Either way, here's an interesting piece of information that I can
give you in return: 

If you take a string of red lights and a string of blue lights and
turn them both on at exactly the same time, then they'll blink
together every 12 seconds.

X^2 - 4x +(4/2^2) + y^2 + 8y + (8/2^2) = -4 + (4/2^2) + (8/2^2)(x + 2)^2 + (y + 4)^2 = -4 + 4 + 16your center is (-2, -4) and the radius is the sqrt of -4 + 4 + 16 which is 4

$7.50x+$4.50y=midk it's been awhile since i've done one of these
