Question

help? >.<
i attached the file below.

Answer 1

Multiply by 2.
Divide by b.

What were you doing?

Answer 2

i still dont get it. i have no idea what im doing. Dx

Answer 3

You are going to have to do better than that. Let's try some warm-ups.

2L = 4

Can you solve for L?

Answer 4

2?

Answer 5

How did you get that?

Answer 6

2 x L equals 4. 2 x 2 equals 4.
(:

Answer 7

Maybe I should say that is correct, except for the "?". Now, let's talk about how you achieved that answer.

You seem to have the idea. "2" and "L" were attached by Multiplication, right?

Answer 8

yes.

Answer 9

Perfect. Now a strange question. What mathematical operation is the opposite of multiplication? Maybe another way to ask...If I MULTIPLY something by 5, what do I have to do to the result to get back where I started?

Answer 10

divide.

Answer 11

Excellent. Now, let's SOLVE my sample problem rather than just magically seeing it.

2L = 4

L is multiplied by 2. I need to divide 2L by 2 to get just L Divide both sides by 2 and see what happens.

(2L)/2 = 4/2

(2/2)L = 2

(1)L = 2

L = 2

We used mathematical operations to acheive the desired result. No guessing. No luck.

Now, let's try your problem.

\(A = \dfrac{1}{2}bh\) -- We need h.

'h' has '2' attached by what?
'h' has 'b' attached by what?
