Answer:
x = 2
y = 12
Step-by-step explanation:
In triangle ABD, CE is the mid segment.
Therefore, by mid segment theorem:
2(5x - 3) = x + 12
10x - 6 = x + 12
10x - x = 12 + 6
9x = 18
x = 18/9
x = 2
Since, DE = EA
2y - 4 = y + 8
2y - y = 8 + 4
y = 12
Answer:

Step-by-step explanation:
<u>Step 1</u>:-
Given problem is [(x + 1)(x - 1)]^2
by using formula in side square bracket is

![[x^{2} -1]^{2}](https://tex.z-dn.net/?f=%5Bx%5E%7B2%7D%20-1%5D%5E%7B2%7D)
<u>Step 2</u>:- again we will use formula

[/tex]
on simplification we get

<u>Final answer:-</u>

<u />
The first step is to subtract 6 from both sides to cancel it out. You will be left with -3x= -1.
