Question

I need some serious help!

Solve S=4v^2 for v

Solve M=2x+3y for y

Solve P= 2(l+w) for l

Answer 1

S=4v^2 for v
S/4 = v^2
v = \[\sqrt{s/4}\]

M = 2x+3y for y
m - 2x = 3y
(m-2x)/3 = y

Solve P= 2(l+w) for l
P = 2l + 2w
p - 2w = 2l
(p-2w)/2 = L

Need any further help with how these answers where obtained?

Answer 2

I believe you can simplify the first one to just sqrtS/2

Answer 3

with a +/_ in front :)

Answer 4

yes you cannot forget that, like i just did. :)

Answer 5

oh wow guys! thanks! i think that's it! You guys helped a lot! :D
