Answer: 19
Answer:
Step-by-step explanation:
Given,
The number of litres consumed by car in (x+20) km = 6,
So, number of litres consumed by car in 1 km = 
,
Now, number of litres consumed by car in 100 km = 100 × litres consumed by car in 1 km
Hence, the rate of fuel used by his car would be 
litres per 100 km.
I believe the answer to be 125 3*, theres a chance im wrong as I am unsure of this, I only know how to get the value which is 5.
The first one is x square +5x-4
The second one is (x-2)(x-8)
