If PM = 2x - 5, PN = 6x, and MN = 5x + 4, what is the value of x?
Vadim26 [7]

Answer:

The required value of x = 3

Step-by-step explanation:

For better understanding of the solution, see the attached figure :

The given three points are collinear to each other and the point P lies somewhere between the end points of the line MN

So, to find the value of x we can use the relation : Sum of Mid segments PM and PN is equal to complete length of the line segment MN

⇒ PN + PM = MN

⇒ 6·x + 2·x - 5 = 5·x + 4

⇒ 8·x - 5·x = 4 + 5

⇒ 3·x = 9

⇒ x = 3

Hence, The required value of x = 3

Calculate the area of the following shape. full answer/explanation please
DerKrebs [107]
To find the area of this entire shape, we must divide it into two rectangles.

The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.

The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.

To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.

8 * 3 = 24 cm^2
3 * 4 = 12 cm^2

24 sq cm + 12 sq cm = 36 square centimeters.

Therefore, the area is 36 square centimeters. Hope this helps! :)
