Denzel wants to walk to the store from his house but he is not sure how far away it is. Find the distance between his house

(-8, -9) and the store (-4, -10). Each unit is equal to one mile. Round your answer to the nearest mile.

22 miles

4 miles

31 miles

17 miles

4 miles

Step-by-step explanation:

Suppose we have two points:

The distance between these points is:

In this question:

Points (-8, -9) and (-4, -10).

So the distance is:

The distance is 4.12 miles.

Rounding to the nearest mile, 4 miles.

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
