I think it’s A because all of the numbers seem to be very close together, unlike the other answers.

3=c/5+2... how do I solve for c??

expeople1 [14]

Primeiro Você IRA Dividir o c (APENAS Colocar 5 + 2 embaixo do c). Depois faça a soma 5 + 2 = 7. Então faça o mmc (mínimo múltiplo comum) entre 7 e 1(o 1 é invisível, mas continua estando embaixo do 3). Deu 7 o mmc. Transforme seus números em frações, com o denominador 7. Transforme os números em frações o 3 virá 21, pois você divide em baixo e multiplica em baixo, e o c continua normal, pois já estava em baixo de 7. Como é para descobrir uma incógnita você tira os denominadores e ficará 21 = c.

3 = c/5 + 2
3 = c/7
21/7 = c/7
21 = c

36 different ways; usually when it asks how many times different outcomes can pop up, all you have to do is multiply is by itself.

Find the limit of the function algebraically. (2 points) limit as x approaches zero of quantity x squared plus two x divided by

DIA [1.3K]

Answer:

DNE

Step-by-step explanation:

$\lim_{x \to \0} \frac{x^{2} +2x}{x^{4} }$

As you can see in the picture I attached to this, that as the limit goes to zero from the negative side, it approaches -∞ and from the positive side, it approaches ∞ . hence, the limit doesn't exist.

To show this algebraically, you have to imagine how a number divided by zero looks like, Just know the graph of 1/x and see how the limit to zero doesnot exist. I hope this helps!
