Answer:

Step-by-step explanation:

Given that 2 parts of the ratio equals 14 green marbles, then divide to find the value of one part of the ratio.

14 ÷ 2 = 7 ← value of 1 part of the ratio, thus there are 7 blue marbles

Total marbles = 14 + 7 = 21

I would just round up to 200 and then subtract twelve or just subtract 200 what ever way u prefer.

By the binomial theorem,

$(2x+y)^4=\displaystyle\sum_{k=0}^4\binom 4k(2x)^{4-k}y^k=\sum_{k=0}^4\binom 4k2^{4-k}x^{4-k}y^k$

where

$\dbinom nk=\dfrac{n!}{k!(n-k)!}$

Then the coefficients of the $x^{4-k}y^k$ terms in the expansion are, in order from $k=0$ to $k=4$ ,

$\dbinom 402^{4-0}=1\cdot2^4=16$

$\dbinom412^{4-1}=4\cdot2^3=32$

$\dbinom422^{4-2}=6\cdot2^2=24$

$\dbinom432^{4-3}=4\cdot2^1=8$

$\dbinom442^{4-4}=1\cdot2^0=1$
