There are 60 girls 20 boys in this equation.
Use the formula a^2+b^2=c^ which is 7.21
The mistake is there is no parenthesis around 4x+12
B, 2 5/8.
2 and 5/8 times itself is 5 1/4, meaning its half of 5 1/4.
Let
. Then
and
are two fundamental, linearly independent solution that satisfy
Note that
, so that
. Adding
doesn't change this, since
.
So if we suppose
then substituting
would give
To make sure everything cancels out, multiply the second degree term by
, so that
Then if
, we get
as desired. So one possible ODE would be
