3. A rock is thrown from the top of a tall building. The distance, in feet, between
the rock and the ground t seconds after it is thrown is given by d(t) = -16t^2 - 4t
+ 382. How long after the rock is thrown is it 370 feet from the ground? *

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:
