Option D is correct.
Step-by-step explanation:
We need to solve by factoring or finding square roots.
We will be solving by factoring.
So, solving by factoring we get x=0 and x=3
So, Option D is correct.

<span>The best way is to find the areas of the bases and the lateral faces separately and add them.
Let's start:
Base area = 14 x 4 = 56
Area of rectangle = 6 x 14 = 84
Area of second rectangle = 8 x 14 = 112
Area of slanted rectangle = 4.47 x 14 = 62.58
Now there are two sides remaining which includes triangles. Seperate the triangles from them and you will be left with 2 small rectangles on the front and back and also two triangles.
Area of two small rectangles = 2( 4 x 6) = 48
Area of two triangles = 4 x 2 = 8
Now add them all,
we get ====> 370.58 Square units</span>

Step-by-step explanation:
Completing the square goes back to pythagorean thm
but the way u do it, u want to find a value that enable u to take sqrt of both sides and solve
x^2-8x+3=0
x^2-8x=-3
we need (x-4)^2 so add 16
(x-4)^2=-3+16
(x-4)^2=13
x-4=sqrt13
x=4(+/-)sqrt13
