Step-by-step explanation:

Khalid : Ahmed

5 : 7

You can think of it as Khalid receiving 5 parts of the total amount of money while Ahmed gets 7 parts of the total amount of money

If Khalid receives $240

This means for the 5 parts she gets $240.

So 1 part = 240/5 = 48

Ahmed receives 7 parts. So multiply 7 by 48

Ahmed = 7 x 48 = $336

$(a+b)^n=\displaystyle\sum_{k=0}^n\binom nka^{n-k}b^k$

where $\dbinom nk=\dfrac{n!}{k!(n-k)!}$ . The third term of the expansion occurs when k=2

.

So the third term of the expansion of (3x^2+2y^3)^4

is

$\dbinom42(3x^2)^{4-2}(2y^3)^2=6(3^2x^4)(4y^6)=216x^4y^6$

The coefficient is 216.
