Look at the time at which you posted this question. Can you guess why no one has answered your question?

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

For the first one : You put X = x² Then you have (variable change) : X² - 6X + 8 = 0 And you use common tools to solve that (use delta). You find X = 2 or X = 4. You have x² = X, so x = sqrt(X) or x = -sqrt(X). Here, the solutions are sqrt(2), -sqrt(2), 2, -2. ...

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...

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 ...
