Answer:
Option B. ![9x^{3}-2x^{2}-4x-2](https://tex.z-dn.net/?f=9x%5E%7B3%7D-2x%5E%7B2%7D-4x-2)
Step-by-step explanation:
we have
![7x^{3}-2x^{2} +5](https://tex.z-dn.net/?f=7x%5E%7B3%7D-2x%5E%7B2%7D%20%2B5)
![2x^{3}-4x-7](https://tex.z-dn.net/?f=2x%5E%7B3%7D-4x-7)
Adds the polynomial
Group terms that contain the same variable

<h3>what is Ratio?</h3>
A ratio indicates how many times one number contains another.
Given:
e:f=3:7
f:g=2:3
Now take LCM of 2 and 7 i.e., 14.
e/f= 3/7= 3*2/7*2= 6/14
and, f/g= 2/3= 2*7/3*7= 14/21
So,
e/g= e/f *f /g
= 6/14*14/21
= 6/21
e:g = 2:7
Hence, the value of e:g is 2:7.
