To answer this, let the 3 sides of the regular sized rectangular box be x, y, and z.
When we double all the sides, the new sides have lengths 2x, 2y, and 2z, respectively.
Since the regular box (with dimensions x,y, and z) have 750 toothpicks, we can write
Similarly we can write for the jumbo box as,
which is equal to 
So this is 8 times the original of 
. Hence the jumbo box will have 8 times 750 number of toothpicks.
ANSWER: 
toothpicks
Plug in -1 for x the solve the equation. 3 * -1 -4(-1) which equals 7
I guess you are asking what is the shape of the cross section.
It will be an ellipse.
To work out the scale factor, divide one of the sides from the larger shape from the smaller shape so:
15/6 = 2.5
So your scale factor would be 2.5
And to check this, multiply 2.5 by 6 and u should get 15, so you know it is correct! :)
Assumin she drank 2 and 1/2 pints of water and not 21/2 pints (because that is alot)
add
2 and 1/2+1/2=2+1/2+1/2=2+2/2=2+1=3
3 pint
