The independent variable is the test hours that he studies; because they are not affected by any of the other variables. The dependent variable is the test score; because the amount of the test score depends on the variable of the studied hours.
t=test score h=hours studied
t+h3
Not sure about the equation though. Might wanna check that. Hope this helps!
All you have to do is add up the side lengths we already know then subtract by the perimeter. 60.3 is the side lengths all together that we know 82-60.3=21.7 Hope this helped!!
