F(x)x^2-2x and g(x)=6x+4 for which value of x does (f+g)(x)=0

(f+g)(x)

Step-by-step explanation:

(f+g)(x)=

c is the correct answer

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.
