Answer: The value of x =2 units.

Explanation:

Since we have given that

AD= CD

BE= EA

So, we get that D and E are the mid-points of AC and AB respectively.

So, by Mid- point theorem , which states that the line joining the two midpoints is parallel to third side and it is half in length of third side i.e.

DE=\frac{1}{2}BC

So, we put the value of DE  and BC ,

5x-3=\frac{1}{2}\times (x+12)\\\\2(5x-3)=x+12\\\\10x-6=x+12\\\\10x-x=12+6\\\\9x=18\\\\x=\frac{18}{9}=2

Hence, the value of x =2 units.

Evaluate y^2 + 2y for y = 0, 1, and 2. Are the resulting numbers prime or composite.
Elza [17]
Y = 0:
(0)^2+2(0)=0+0=0
0 is neither prime nor composite.

y=1:
(1)^2+2(1)=1+2=3
3 is a prime number (because only 3 and 1 divide evenly into it)

y = 2:
(2)^2+2(2)=4+4=8
8 is a composite number (because multiple different numbers divide evenly into it: 1, 2, 4, and 8)
