Using the following image, solve for x

-3

Step-by-step explanation:

According to the question,

CE = CD + DE

8 = (x + 10) + (x + 4)

8 = x + 10 + x + 4

8 = 2x + 14

8 ― 14 = 2x

―6 = 2x

―6 ÷ 2 = x

–3 = x

Therefore, the value of x is ― 3.

the answer is 288..

hope this

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
