Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Hmm. Are you trying to solve for b? And do you have values for A/h/c or do you just want it in terms of A, h, and c?

ok here it is...i got b=2A-c

gfa -- you seem to have missed h'.

thanks

I am just having a hard time with this class

So the steps are: \begin{align} A &= \frac{1}{2}h(b + c)\\ 2A &= h(b+c)\\ \frac{2A}{h} &= b + c\\ \frac{2A}{h} - c &= b \end{align} First you multiply both sides by 2 to cancel out the 1/2. Then you divide both sides by h to cancel out the h on the right. Then you subtract c from both sides. Finally, b is alone :)

Feel free to ask any other questions. Hopefully that grade can go back up :) Algebra can be tough, but if you keep pushing it'll make more and more sense.
