Hey there! :D

When a fraction is still divisible by a number, then it is not in it's simplest form.

For example, 3/6.

I know for a fact that 6/3=2 <== 3 is also divisible by itself.

3/6 (3/3=1) (6/6=1)

1/2 <== simplest form.

Try the same with 2/4.

4 is divisible by 2.

4/2= 2

2/2=1

1/2 is the simplest form.

I hope this helps!

Hey there!

In this fraction, we can imagine a circle, divided into four parts. One half of the circle with two parts, and the other half with another two. Shading in one is 1/4, and shading another would be 2/4. When we imagine this, we see that half the circle is filled, therefore it's not in simplest form. If we divide the top by 2 and bottom by two, we get the same answer as we've seen in our picture. It's equal to one half.

Hope this helps!

Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth

Anika [276]

Answer:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the quadratic formula is:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. To solve the quadratic equation you must substitute the values. So, you have that:

Rewrite the equation:

$2x^{2}-5x-1=0$

$a=2\\b=-5\\c=-1$

Then you have:

$x=\frac{-(-5)+/-\sqrt{(-5)^{2}-4(2)(-1)}}{2(2)}$

3. Therefore, you obtain the following result:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

Can someone help me? thanks!

So you know that 1 cubic foot is equal to 80 pounds. So, the first point would be (1,80).
You can find the other points by multiply 80 by a number, and when I did that, I got (2,160) and (3,240) too.

I hope this helps :)
