How can you simplity x^2+2x-35/x^2+4x-21?
Divide the numerator and denominator by (x-21)
Divide the numerator and denominator by (x+7).
Divide the numerator and denominator by (x-3)
Divide the numerator and denominator by (x - 5)

Step-by-step explanation:

Factor the numerator(x+7)(x-5). Then factor the denominator(x+7)(x-3). The x+7 in the top and bottom cancel. So you are left with x-5 in the numerator and x-3 in the denominator.

step-by-step explanation:

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
