If d is the midpoint of ce, ce=10x+18 and de=7x-1, find x

7 0

Given that D is the mid point of CE ,

So D will bisect CE, it means the length of DE and CD is equal.

=> DE + CD = CE

As DE and CD are equal,

=> DE + DE = CE

=> 2 DE = CE

Putting values from the question,

=> 2( 7x - 1 ) = 10x + 18

=> 14x - 2 = 10x + 18

=> 14x - 10x = 18 + 2

=> 4x = 20

=> x = 20 / 4

=> x = 10 / 2

=> x = 5

$.$

Therefore, the value of x is 5

X = 5 which gives you your answer. Sorry for no work I'm not sure how to do it.

What is the area of this shape?

Dovator [93]

Answer:

The area of this shape equals $30cm^{2}$

Step-by-step explanation:

From the diagram, we can see that this shape is a parallelogram (since opposite sides are equal to each other). The formula for the area of the parallerlogram is as follows:

$Area = bh$ (where "b" is the base, and "h" is the height).
