D. -3 because you first find k(2) which is -2 and plug it back into the h(x) formula to get 3/-1 which is -3
Answer:
C
Step-by-step explanation:
I’m not entirely sure if this is right but I hope I helped.
Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
20 imperial gallons = 90.9218 litres
so i'd say you'd need to buy 91 bottles or...
20 US Liquid gallons = 75.7082 litres
so you'd have to buy 76 bottles.
Hope this answers your question! It depends what gallon you're working from.
