The following list gives the coefficients for the binomial expansion of (x + y)10. what is the value of b?

1, 10, 45, 120, 210, 252, 210, b, 45, 10, 1

1
10
45
120

The coefficients for the binomial expansion are symmetric across the middle term.

For the binomial expansion you will get 10+1=11 coefficients. The 6th term is middle term. If the coeeficients are

1, 10, 45, 120, 210, 252, 210, B, 45, 10, 1,

then the 6th term is 252.

This means that

If 4th and 8th terms are the same, then B=120.

correct choice is D

triangle and cube

step-by-step explanation:

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
