It's a rational number. It's the ratio of -53 to 12,and it can be written as
the fraction -53/12 .

<u>Hint:</u>
<em>ANY</em> number that you can completely write down on paper with digits
is a rational number.
Nobody ever tells you this, but I thought it'll be useful for you to know.

Answer:

$\frac{ {x}^{2} + 10x + 16 }{ {x } {}^{2} + 6x + 8} \div \frac{1}{x + 2}$

$\frac{ {x}^{2} + 8 x+ 2x + 16}{ {x}^{2} + 4x + 2x + 8} \times (x + 2)$

$\frac{x(x + 8) + 2 (x + 8)}{x(x + 4) + 2(x + 4)} \times (x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 2)(x + 4)} \times ( x + 2)$

$\frac{( x + 8)(x + 2)}{(x + 4)}$

Is (5x+4) a factor of (-21x^2-15-40x+5x^3

Tamiku [17]

Answer:

No. It is not.

Step-by-step explanation:

Dividing 5x³+21x²-40x-15 by 5x+4 gives x²+5x-4 with a remainder. Which means, 5x+4 is not a factor of 5x³+21x²-40x-15
