Find the value of the variable and gh if h is between g and i. gi = 8b + 1, hi = 3b – 2, hi = 4 a b = 2, gh = 17 b b = 2, gh = 13 c b = 0.45, gh = 4.64 d b = 0.38, gh = 3.13

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

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.
