Given f (x) = 2x^3 – 6x+k, and the remainder when f (x) is divided by x +1 is 7, then what is the value of k?

da freeck kinda math is this just drop out

step-by-step explanation:

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.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
