Here's the question:
Solve P=2L+2w for L
Here's what I came up with:
P=2(L+w)
P/2=L+w
P/2-w=L

P = 2L + 2w
Subtract 2w both sides,
P - 2w = 2L
Multiply both sides by (1/2),
(1/2)(P - 2w) = L
Which is equivalent to your answer.

Correct, but kind of the long way around:
2L = P - 2W
L = P/2 - W

Congratulations. This is the first homework-helper question in the history of Yahoo! Answers where the sender actually applied effort to it first. And you got it right. Good work!

P=2L+2w.....given
So, 2L=P-2w
Dividing both sides by 2, we get
L = P/2 - w
THAT CONFIRMS YOUR ANSWER !

That is correct!
You could also do
P-2w=2L then divide by 2
L=(P-2w)/2...same thing :)

The first answer is D, because cell plates are present in plant cells, not animal cells. Because you know the cells are plant cells, the answer to the second question is A, you're correct. Centrioles are not present in plant cells.

I would say (P-2W)/2 = L

2L = P - 2W
L = P/2 - W
