Solve by using square root: <br> 4(x-1)^2+2=10

Scilla [17]

$4(x-1)^2+2=10\\\\4(x^2-2x+1)+2-10=0\\\\4 x^2-8x+4+2-10=0\\\\4 x^2-8x-4=0\ \ / :4\\\\x^2-2x-1=0\\\\x_{1}=\frac{-b-\sqrt{b^2-4ac}}{2a}=\frac{2-\sqrt{ (-2)^2-4*1*(-1)}}{2 }=\frac{2-\sqrt{ 8}}{2 }=\frac{2- \sqrt{ 4*2}}{2 }=\\\\=\frac{2-\sqrt{ 8}}{2 }=\frac{2(1- \sqrt{ 2})}{2 }=1- \sqrt{ 2}\\\\x_{2}=\frac{-b+\sqrt{b^2-4ac}}{2a}=\frac{2+\sqrt{ (-2)^2-4*1*(-1)}}{2 }=\frac{2(1+ \sqrt{ 2})}{2 }=1+ \sqrt{ 2}$

$Answer:\ x=1- \sqrt{2}\ \ or\ \ x= 1+ \sqrt{ 2}$

You are wrapping a gift box. You want to tie a ribbon around the box , so that whenever the ribbon intersects an edge of the box

Paha777 [63]

You are wrapping a gift box. The length of ribbon = length + width + height of box.

<u>Solution:</u>

Given, You are wrapping a gift box.

You want to tie a ribbon around the box, so that whenever the ribbon intersects an edge of the box, its distance to the nearest corner is 1/3 the length of the box.

We have to find how long must the ribbon be?

The figure of this problem is attached below

Now, assume we started to tie at one edge, then next we can tie at straight parallel edge, we can continue till our process ends.

Then, total length of the ribbon = length of box + width of box + height of box.

Hence, the length of ribbon = length + width + height of box.

Megan uses 2/3 cup of almonds to make 4 cups of trail mix. Using the same porportion,how many cups of almonds would Megan need t

Viktor [21]

Okay so let's make this fraction bigger. 2/3 x 2 would equal 4/6 which means megan uses 1/6 per cup of trail mix. so if she wanted to make 9 batches of trail mix she would use 2 1/6 but let's make that into an improper fraction.. aka 13/6 .. we cannot simplify that so megan would need 2 1/6 cups of almonds
