Which equation is true? Explain your answer.
Liula [17]

Answer:

<h2>12/36</h2>

Step-by-step explanation:

1. Find if all of the fractions are equal to the other fraction next to them.

First, let's go with the denominator of all.

6/8 = 4/3

First of all, we can easily say that this is not right, since the fact that, 6 is less than 8, and 4 is greater than 3. That's just signaling that this can't be the answer.

3/5 = 8/10

10/5=2

8/3=??? (doesn't go into 8)

So, this one is also wrong

12/16 = 36/48

48/16=3

36/12=3

<h2>So hence, the last one or 12/16=36/48 is RIGHT.</h2>

Well I'm having troubles with something I have no idea what it is or how to do it. The problem is x^2 -18x+8=0. I only know how
Lubov Fominskaja [6]

Answer:

x = \frac{-(-18) -\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 -2 \sqrt{73}}{2}= 9 -\sqrt{73}

x = \frac{-(-18) +\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 +2 \sqrt{73}}{2}= 9 +\sqrt{73}

Step-by-step explanation:

We have the following equation:

x^2 -18 x +8 =0

We can use the quadratic formula given by:

x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}

Where:

a = 1 , b=-18, c =8

And replacing we got:

x = \frac{-(-18) -\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 -2 \sqrt{73}}{2}= 9 -\sqrt{73}

x = \frac{-(-18) +\sqrt{(-18)^2 -4*1*8}}{2} = \frac{18 +2 \sqrt{73}}{2}= 9 +\sqrt{73}
