Using the shortcut for binomial expansion, which still took 45 minutes, I got 23-26. The coefficient on the x^6 term is 34,020; the coefficient on the x^4 term is -495; on the x^7 term it's 1800; on the x^3 term it's 337,920. I'm pooped. The rest is factorial notation, kinda the same thing, but...

Hi there!

So we know that the two train together is a total of 192 tons and the difference of their weights is 120 tons...

Ok let think...

When we’re looking at the once place, you’ll see a two... this means that the two train both have a ending of 1 since 2 is split into 1...

That would be another clue..

Now let think again...

If it would be 151 and we subtract by 120.. we would get...

$151-120=31$

Well it ends with a 1 so it would be perfect but we have to see if 151 and 31 together adds up with the total of 192..

$151+31=192$

This means that train A could be 151 tons or 31 tons and train B can also be wither 151 tons or 31 tons...

The correct answer is letter C; -6,
-5 2/5 or -27/5 and -4 1/5 or -21/5.

You can find this answers by substituting 1, 4, and 10 into the letter n.

Then you follow the operational order to get the answer.

what is the surface area of a rectangular prism that has a height of 5cm a width of 10cm and a depth of 4cm

Kamila [148]

2(5*10)+2(10*4)+2(5*4)=

2(50)+2(40)+2(20)=100+80+40=

220 cm^2

I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.
