In two or more complete sentences, analyze how to find the third term in the expansion of (2x + y)4.

The third term in the expansion of the given expression us:

Step-by-step explanation:

We are given an expression as:

We know that by using the binomial theorem the expansion of the expression of the type:

is given by:

This means that there are n+1 terms in the expansion of the type:   

such that the rth term is:

Here we have:

   n=4,a=2 and b=1

Now, the third term in the expansion of the given expression is:

the answer will be

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
