Aship leave port and sails 12 km west, then 19 km north. approximately how far is the ship from the port?

22Km

Step-by-step explanation:

H^2=19^2+12^2

H^2=361+144

H^2=505

Then find the square root of both sides

H=Square root(505)

H=22km(to a whole number)

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

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
