1. The solution of the equation is the third option. 2. The equation has no real solution because the answers are both imaginary numbers. 3. The side length of a square with an area of 144x² is 12x. 5. The value of z so that 9 and -9 are both solutions is equal to 22.
Here is how this is solved. First stage one segment second stage 3 segment each 1/3 of the original (like dividing the first one into 3) this creates three bending 3rd stage each one of the 1/3 long segments is now divided into 4 making a total of 12 low and behold there is 12 bendings in total the idea here is each division is considered a bend
