Choose the simplified form of  the fifth term of 6C4(2x)2(-y2)4.​
Katarina [22]

You didn't give us the choices.   It doesn't matter.  I think you're trying to write

\displaystyle {6 \choose 4} (2x)^2 (-y^2)^4

= \dfrac{6!}{4! 2!} ( 4x^2 y^8)

= \dfrac{6(5)}{2} ( 4x^2 y^8)

=60x^2 y^8

Answer: 60 x² y⁸

Metro trains contain 330,000 tons of CNG

3300 tons of diesel was saved

21000 tons of petrol was saved at the end of 2007

(I) The fraction of the quantity of diesel saved to the quantity of petrol saved can be calculated as follows

= 3300/21000

= 11/70

(II) The fraction of the quantity of CNG saved to the quantity of diesel can be calculated as follows

= 3300/33000

= 1/10
