Answer:
![\frac{b-10}{b-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bb-10%7D%7Bb-1%7D)
Step-by-step explanation:
We start by factoring out all polynomials in the expression:
![\frac{b^2-2b-8}{b^2+b-2} -\frac{6}{b-1} =\\=\frac{(b-4)(b+2)}{(b+2)(b-1)}- \frac{6}{b-1}=\\](https://tex.z-dn.net/?f=%5Cfrac%7Bb%5E2-2b-8%7D%7Bb%5E2%2Bb-2%7D%20-%5Cfrac%7B6%7D%7Bb-1%7D%20%3D%5C%5C%3D%5Cfrac%7B%28b-4%29%28b%2B2%29%7D%7B%28b%2B2%29%28b-1%29%7D-%20%5Cfrac%7B6%7D%7Bb-1%7D%3D%5C%5C)
where we can simplify the factor (b+2) that appears in numerator and denominator of the first rational expression, to reduce it to:
![\frac{b-4}{b-1} -\frac{6}{b-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bb-4%7D%7Bb-1%7D%20-%5Cfrac%7B6%7D%7Bb-1%7D)
Now we can combine both rational expressions since they share the same denominator:
![\frac{b-4}{b-1} -\frac{6}{b-1} =\frac{b-4-6}{b-1} =\frac{b-10}{b-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bb-4%7D%7Bb-1%7D%20-%5Cfrac%7B6%7D%7Bb-1%7D%20%3D%5Cfrac%7Bb-4-6%7D%7Bb-1%7D%20%3D%5Cfrac%7Bb-10%7D%7Bb-1%7D)

74.75 for 5 gallon unit rate
74.75 / 5 = 14/95
Answer: $14.95 per gallon of paint
Therefore, about 15 dollars per gallon of paint since we need to estimate.
y = 3x-2x∧2+5x∧3
When we replace x with value 3 we get
y = 3 * 3 - 2 * 3∧2 + 5 * 3∧3 => y = 9-2*9+5*27 => y = 9-18+135 => y = 126
good luck!!!
