Answer:
x = 2 is the solution of the given equation
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given equation

squaring on both sides , we get

⇒ x + 2 = x²
⇒x² - x -2 =0
<u><em>Step(ii)</em></u>:-
Given x² - x -2 =0
⇒ x² - 2x + x - 2 =0
⇒ x ( x-2) + 1(x - 2) =0
⇒ (x + 1) ( x-2) =0
⇒ x = -1 and x =2
x = 2 is the solution of the given equation
<u><em>Verification</em></u>:-

Put x= 2


2 = 2
The answer is b
The way I do it is the area of the front back times 2 which is 2x4x2=16
Then top and bottom times 2 which is 4x8x2=64
Then left and right which is 2x8x2=32 then you add them all together so 16+64+32=112
Hope this helped :)
