A line AB joins the points A (3,4) and B (5,8). Write down the coordinates of the midpoint of the line AB Please help
Thank you

Given:

A line AB joins the points A (3,4) and B (5,8).

To find:

The midpoint of the line AB.

Solution:

Midpoint formula:

A line AB joins the points A (3,4) and B (5,8). So, the midpoint of line AB is

Therefore, the midpoint of the line AB is (4,6).

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

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
