The rectangle below has an area of x2 – 6x – 7 square meters and a width of x– 7 meters. What expression representsthe length of the rectangle?

777777777777

Step-by-step explanation:

888888888888km

The length is (x+1)

    Step-by-step explanation:

We know the area equals length times width. LxW=Area

We know the width equals (x-7). We also know the area equals x² - 6x - 7.

We need to expand the area. When we do, we get (x+1)(x-7).

The width is (x-7), so the length must be (x+1)

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
