Question

Solve S = 4v2 for v.
-4(4-v)= -2(2v-1)
v-16+4v = -2(2v-1)
v-16+4v = -4v + 2
-16+5v = -4v + 2
5v = -4v + 18
9v = 18
v = 2

Did i do this right??

Answer 1

69

Answer 2

What?

Answer 3

So

Divide by 4 to get s/4=v^2

Take the square root to get:

v=+/- sqrt(s)/2

Answer 4

What?? O.o Sooo confused

Answer 5

S = 4v^2
We can do the same operation to both side of the equation and it will still be equal. We divide by 4.

Answer 6

S/4 = v^2
Now we take the root of both sides.

sqr(S)/2 = v
And that is the answer, if my guess was correct about v^2.

Answer 7

Honestly i got this answer from someone else. But wasnt sure if they were correct because i dont know how to solve this problem at all. So i really do not understand what your saying. I just started doing algerbra 2 online and it didnt show how to solve a problem like this

Answer 8
