Question

Solve S = 2LW + 2LH + 2WH for H.

Answer 1

The first step would be to try to isolate "H" on one side of the equation.

Answer 2

Or any terms with "H" in them.

Answer 3

How would I start off?

Answer 4

S = 2LW + 2LH + 2WH

I see that "2LW" does not have an "H" in it, so I will subtract it from both sides.

S - 2LW = 2LW - 2LW + 2LH + 2WH

S - 2LW = 2LH + 2WH

Can you continue?

Answer 5

Would the answer be S - 2LW / 2LW = H ??

Answer 6

Hm, I think you're missing a term there. Where is the 2W from 2WH?

Answer 7

What?

Answer 8

You're missing a term.
Can I see your work?

Answer 9

S = 2LW + 2LH + 2WH

S - 2LW = 2LW - 2LW + 2LH + 2WH

S - 2LW = 2LH + 2WH

S - 2LW / 2LW = H

Answer 10

There's a mistake from step 3 to 4.
Looking at step 3, to isolate "H" what can you do? Or what did you do?

Answer 11

I divided 2L and 2W to get H alone.

Answer 12

Have you learned common factoring?
You can common factor the "H" out on the right side in step 3.

Try that.

Answer 13

Since both terms have an "H" in them, you can free the "H" by common factoring.

Answer 14

How?

Answer 15

S = 2LW + 2LH + 2WH

S - 2LW = 2LW - 2LW + 2LH + 2WH

S - 2LW = 2LH + 2WH

S - 2LW = H(2L + 2W) Does this step make sense?

Answer 16

Ohh

Answer 17

:D

Answer 18

Lol thank you for being patient with me.. I'm having a little trouble because I've had a weird day. :)

Answer 19

Don't worry about it, you should see how hopeless I am on the physics section. :P People must pull their hair out while trying to help me.

Answer 20

Lol. Yikes! Good luck with that!! :D
