Simplify -12x^4/x^4+8x^5
alexgriva [62]

Answer:

OPTION A: $ \frac{12}{1 + 8x} $, where $ x \ne - \frac{1}{8} $.

Step-by-step explanation:

Given: $ \frac{- 12x^4}{x^4 + 8x^5} $

Taking $ x^4 $ common outside in the denominator, we get:

$ = \frac{-12x^4}{(x^4)(1 + 8x)} $

$ x^4 $ will get cancelled on the numerator and denominator, we get:

$ = \frac{-12}{1 + 8x} $

we know that the denominator can not be zero.

That means, 1 + 8x $ \ne $ 0.

$ \implies 8x \ne -1 $

$ \implies x \ne \frac{-1}{8} $

So, the answer is: $ \frac{-12}{1 + 8x} $, where $ x \ne \frac{-1}{8} $.

Are these two figures congruent? Why or why not?
AnnZ [28]
Yes they are congruent because they have just been translated in a rotation. But they still hold the same area and perimeter.
