solve 25m^2-16=0 :P

OpenStudy (anonymous):

20m^2 = 16 m^2 = 16/20

OpenStudy (anonymous):

that's somewhat incorrect, 25m^2 = 16 m^2 = 16/25 m = sqrt ( 16 / 25) m = +- 4/5

OpenStudy (anonymous):

yes I also thought maybe if it was 25, the answer would be correct.

OpenStudy (anonymous):

heh you read the 20 wrong, it was 25. =P

OpenStudy (anonymous):

thats what it said in the book

OpenStudy (anonymous):

yup.

OpenStudy (anonymous):

heh ty. =P
