Write your height in inches. Suppose it increases by 15%, what would your new height be? Now suppose your increased height decreases by 15% after the 15% increase; what is your new height?

New height= 41.4 inches

Second new height= 36inches

Step-by-step explanation:

Height is assumed to be 36 inches

If it increases by 15%.

15%= 0.15

It's new height =( 36*0.15) +36

New height= 5.4+36

New height = 41.4 inches

This expression (36*0.15) is the expression of adding 15% to the height.

So if the 15% is taken away again , height= 41.4-(36*0.15)

Height= 41.4-5.4

Height= 36 inches

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
