Answer:

x = 2 is the solution of the given equation

Step-by-step explanation:

Step(i):-

Given equation

$\sqrt{x+6-4} = x$

squaring on both sides , we get

$(\sqrt{x+2})^{2} = x^{2}$

⇒ x + 2 = x²

⇒x² - x -2 =0

Step(ii):-

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

Verification:-

$\sqrt{x+6-4} = x$

Put x= 2

$\sqrt{2+6-4} = 2$

$\sqrt{4} = 2$

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 :)
