OpenStudy (diyadiya):
\[A=\frac{1}{2}h(B+b) \]
is this the equation ?
OpenStudy (anonymous):
yes, i couldnt figure out how to make he h in the middle
OpenStudy (diyadiya):
Ok so first multiply both sides by 2
OpenStudy (diyadiya):
\[2 \times A = 2 \times \frac{1}{2}h(B+b)\]
OpenStudy (diyadiya):
Now what happens to the 2's in the right side?

do they cancel out?
OpenStudy (diyadiya):
Yes!!
OpenStudy (diyadiya):
Now what do you have ?
OpenStudy (anonymous):
2xA=h(B+b) ?
OpenStudy (diyadiya):
Right!! :)

Now you have to isolate h
what do you think you can do ?
OpenStudy (anonymous):
do you subtract the h from both sides?
OpenStudy (diyadiya):
Nope
its multipplication so you cant subtract it
we divide both sides by (B+b)
OpenStudy (diyadiya):
2A = h x (B+b)
so divide both sides by (B+b) so that we can isolate h (since (B+b) will cancell out )
OpenStudy (anonymous):
2xA/B+b the other cancells out correct?

yes!!! :)\[\Huge h= \frac{2A}{(B+b)}\]
OpenStudy (anonymous):
just 2A i didnt need the multiply sign anymore got it
OpenStudy (diyadiya):
:)

ty, that made it easy your the best!
