B:2x^2+3x=4x+12
C:2x^2+4x+12=0
D:2x^2+4x=0

Step-by-step explanation:

hello :

help : ax²+bx+c=0 ( a≠ 0 )

calculate : Δ = b²-4ac    if Δ<0 you have non real solutionscontinu

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.
