geometry?
If you are comparing similar geometrical figures, the answer is b). Your question seems to be about geometry, not agebra.

I walk 3.5 kilometers every day. How far do I walk in days? Write this answer in meters!
Thursday, December 18, 2008 at 7:35pm by Taylor

Pre- Agebra
a kilometer is 1000 meters. 3.5km is 3500 meters. A centi is 1/100. 345cm=3.45m

Pre- Agebra
1 km = 1,000 meters Multiply: 3.5 * 1000 = ? meters walked per day

agebra
4^(n+1) = 2^[2*(n+1)]= 2^(2n+2) 8^(n-2)= (2^3)^(n-2) = 2^(3n-6) If the 8^(n-2) is supposed to be in a denominator, 2^n * 4^(n+1) ____________ 8^(n-2) = 2^(n + 2n + 2 -3n +6) = 2^8 = 256 no matter what n is. Pick a value of n and prove it for yourself.

Hmmm. Have you any clues? what is the correct answer? see any mistakes in my agebra? If you go to wolframalpha.com and type in derivative y/(x+4y) = x^4 – 4 you will see the value of y', which is what I got above. So, if my answer is wrong, I must have erred in my evaluation ...

For the first one : You put X = x˛ Then you have (variable change) : X˛ - 6X + 8 = 0 And you use common tools to solve that (use delta). You find X = 2 or X = 4. You have x˛ = X, so x = sqrt(X) or x = -sqrt(X). Here, the solutions are sqrt(2), -sqrt(2), 2, -2. For the second ...

L=laser tag, V=video games 3L+5V=17 (1) 4L+7V=23 (2) Since the question asks only about the video games, we want to eliminate the L's. We can do this by multiplying the first equation by 4 and the second equation by -3. 12L+20V=68 (3) -12L-21V=-69 (4) Add 3 and 4 together. -V...

substitution is a poor choice for your equations, elimination is the obvious way to go add 1st and 2nd --> -z = 7 z = -7 sub that into 2nd --> -x - y = 9 sub z=-7 into 3rd --> -x + y = 25 (I will assume the 32 is a typo, and you meant 3z ) now add these last two ...
