Ihave ten minutes left! what is the coefficient of the last term in the binomial expansion of (x+1)^9? a) 0 b) 1 c) 9 d) 10

B. 1

Step-by-step explanation:

This is because a coefficient not because there is a 1 in the equation but because a coefficient is the number before a variable

Examples:

4x-8 4 is the coefficient

5+8x 8 is the coefficient

My teacher always said there is an invisible 1 before each variable

So basically (1x+1)^9 is your equation but the one is hidden.

I hope this helps!

one that is bigger than 3 1/2
