Yep! The answer is 9
When using the Pythagorean theroem, you use a^2+b^2=c^2
Because c represents the hypotenuse, c=15
and a=12
12^2+b^2=15^2
144+b^2=225
b^2=81
b=9
I hope this helps!
Formula for compound interest is
Interest = Amount - Principal
Interest = - P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = - 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = - 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
