It's the 3rd option. All your doing to me, is adding all the numbers straight down. I think you meant to write it like this: 8x² - x - 4
X, x+1, x+2, x+3 - four consecutive integers

The integers are 169, 170, 171 and 172.
Question: Michelle's family drove 272.48 miles . Michelle's calculate that they drove 26.2 miles per gallon of gas how many gallons of gas did the car use=> Unit rate = 26.2 miles per gallon,Now the total number of miles that they need to travel is 272.48 miles.Let's divide the total number of miles by the number of miles per gallon.=> 272.48 miles / 26.2 miles per gallon = 10.4 gallonThus, they need a total of 10.4 gallon in 272.48 miles.<span>

For the largest area, half the fence is used parallel to the river, and the other half is used for the two ends of the rectangular space.
The dimensions are 475 m by 237.5 m.
_____
Let x represent the length along the river. Then the area (A) is found as
.. A = x*(950 -x)/2
This equation describes a parabola with its vertex (maximum) halfway between the zeros of x=0 and x=950. That is, the maximum area is achieved when half the fence is used parallel to the river.
Check the picture below.
recall that in a square, all sides are equal, so if we make b = a, then we get that for one side, also recall that the area of a rectangle is length*width, so in this case,
