Order from least to greatest, 1.021,1.2,1.14,1.009

the answer is c

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
