(x-1)(x-1)
=x^2-x-x+1
=x^2-2x+1
(x+7)(x-7)
=x^2-7x+7x-49
=x^2-49
The last gas station she stopped at she got 6.6 gallons and paid $20.39
If they lower the price by 6%, that means she would pay 94% of the original amount ( 100% - 6% = 94%)
Multiply the amount she paid by 94%:
20.39 x 0.94 = 19.17
She would pay $19.17 total.
Now divide that by the number of gallons bought:
19.17 / 6.6 = $2.90 per gallon ( Rounded to the nearest cent).
Answer:
14641
Step-by-step explanation:

36 miles an hour
3miles/5min to x/60min multiply top and bottom by 12 and you get 36miles/60min
Step-by-step explanation:

vertical asymptote indicates the denominator part and the x-intercept the nemominator and you multiply it by variable b then give the value of x 0 to get y-intercept =b(-12/8)=9
b=-6
