r=2

r^2-2r-2r+4=0

r(r-2)-2(r-2)=0

(r-2)(r-2)=0

r=2,2

On my sister's 15th birthday, she was 159 cm in height, having grown 6% since the year before. How tall was she the previous yea
Zarrin [17]
It means that her height in this year is 106\%x in regards to the last year, where x is her height in last year, so:

159=106\%x

159=\frac{106}{100}x

159=\frac{53}{50}x

159*50=53x

159*50=53x

7950=53x

150=x
