ANSWER

EXPLANATION
The given binomial expansion is:

Compare this to

we have a=2x , b=-3y and n=10
We want to find the coefficient of the term

This implies that, r=5.
The terms in the expansion can be obtained using

We substitute the given values to obtain;



Hence the coefficient is;

Answer:
C
Step-by-step explanation:
because vertical angles angles that are opposite each other and formed by two intersecting lines are congruent
hope this helps :D
You move the decimal to the left three places, so it is 10³
