The midpoint of AB is M(0, -3). If the coordinates of A are (2, -5), what are the coordinates of B?

(-2, -1)

Step-by-step explanation:

To get the coordinates of B, you need to double the distance from the midpoint to A. The difference of 2 and 0 is 2, and the difference between -5 and -3 is 2. So you need to move 2 along the x and y axis. That would give you (2, -1)

Point B is at (-2,-1)

Step-by-step explanation:

Let's draw this nice and easy:

In the picture we can see that the difference in A to the midpoint is +2 y and -2 x so it is (0-2, -3+2) = (-2,-2)

answer: i'm not sure

step-by-step explanation:

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
