Which one of the following options is true when considering the expansion of the binomial expression (x+y)4?

A. The last term of the expansion of (x+y)4 is y4.

B. The coefficients of the expansion of (x + y)4 are: 1, 4, 4, 1.

C. The expansion of (x + y)4 will yield 4 terms.

D. The sum of the exponents of each term of the expansion of (x + y)4 is 5.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
