Answer:

The mistake is that the equation on both sides is multiplied by 8. Both sides should be divided by 8.

Step-by-step explanation:

$8x^2-x-1=0$
$8x^2-x=1$ Divide both sides of the equation by 8
$x^2-\frac{1}{8} x=\frac{1}{8}$
$x^2-\frac{1}{8} x+?=\frac{1}{8} +?$ Add the same value to both side
$x^2-\frac{1}{8} x+\frac{1}{256} =\frac{1}{8} +\frac{1}{256}$
Use $a^2-2ab+b^2=(a-b)^2$
$(x-\frac{1}{16} )^2 = \frac{33}{256}$
$x-\frac{1}{16}=+-\frac{\sqrt{33} }{16}$
$x_{1} =\frac{-\sqrt{33}+1 }{16}$
$x_{2} =\frac{\sqrt{33}+1 }{16}$

Find the length of the diameter of a sphere with a surface area of 50.27 ft^2.

Liula [17]

Sphere Surface Area = 4 • π • r²

50.27 = 4 * PI * r^2

50.27 / (4 * PI) = r^2

 4.0003594946 = r^2

r = sq root ( 4.0003594946)

radius = 2.0000898716 

So the diameter = 4.0001797433 

or it is roughly 4 feet
