Using the quadratic formula to solve 4x^2 – 3x + 9 = 2x + 1, what are the values of x? a: 1+-sqrt159i/8b: 5+-sqrt153i/8c: 5+-sqrt103i/8d: 1+-sqrt153i/8

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

they disappear if your absent from to long. i found out that the hard way.
