Answer:
he owed $4
Step-by-step explanation:
Ben borrowed twenty dollars to spend, and 20 is above 16, so his savings is immediately gone. He owes four dollars because that's how much he needs even after using up his savings.
There are 4 quarts in a gallon. 4 times 5 is 20 and 28 divided by 20 is 1.4. So the cost of one quart of the oil is $1.40
Answer:

Step-by-step explanation:
Start by factoring out a -1...

Now, we have to find two integers that multiply to get -16 and have a sum of 6:
(-2)*8=-16
-2+8=8-2=6
Using this, we can split 6x into -2x and 8x...

Factor the first and second half separately...
![f(x)=-[(x^2-2x)+(8x-16)]\\f(x)=-[x(x-2)+8(x-2)]\\](https://tex.z-dn.net/?f=f%28x%29%3D-%5B%28x%5E2-2x%29%2B%288x-16%29%5D%5C%5Cf%28x%29%3D-%5Bx%28x-2%29%2B8%28x-2%29%5D%5C%5C)
Since both x and 8 are being multiplied by x-2, we can combine them to get...
