Geometry need help fast

Step-by-step explanation:

a union b is equal to bracket {1 ,2, 3, 5, 7, 9} intersection b equal to {3 ,5}

(A U B)'=U-AUB

={4,6,8}

B'=U-B

{2,4,6,8}

A intersection B'={2}

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.
