If ( x + y )^3 is expanded, what is the sum of the numerical coefficients?

8

Step-by-step explanation:

We know that , can be written in expanded form as .

Similarly , can be written in expanded form as .

The numerical coefficients are basically the constant multiplier in the variables in each term.

The numerical coefficient for term  =  1

The numerical coefficient for term  =  1

The numerical coefficient for term  =  3

The numerical coefficient for term  =  3

Then, the  sum of the numerical coefficients =1+1+3+3 =8

Hence, the sum of the numerical coefficients is 8.

b

d

step-by-step explanation:

the answer would be c:   ax + b = ax + c
