Expand the following equation: 6(x+2)
6(x+2) 6x+6(2) 6x+12
In the following equation, solve for 'x'. 5x = 55
5x = 55 (5x)/5 = 55/5 x = 11
Why is the sky blue?
The reason the sky is blue is due to three simple techniques of the world. The first thing that makes the sky appear blue is the sunlight we see is made of different wavelengths. The atmosphere, which is the second technique, acts like a pair of sunglasses and filters out different wavelengths. Finally, due to the sensitivity of our eyes and which wavelengths are absorbed and reflected, we see the sky as blue.
