Answer:
9.9 gallons
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (250, 275, 9) as shown below:

Next we cross multiply. We multiply 250 and x, and we multiply 9 and 275.


Now, lets put the values above back into the equation:

Lets solve this equation. First we divide 2,475 by 250, making x by itself.


This means that to drive 275 miles, Kala would need to use 9.9 gallons of gas.
You first need to cross multiply to get 8x+8=6x^2-6. Then make the function into 6x^2-8x-14=0 which can be simplified into 3x^2-4x-7=0 by dividing the equation by 2. Then you must split the middle(-4x) to get 3x^2+3x-7x-7=0. This simplifies to 3x(x+1)-7(x+1)=0 and then to (3x-7)(x+1)=0. From here you just solve for each root which you will find are x= -1 and 7/3
