In simplest radical form, what are the solutions to the quadratic equation 6 = x2 – 10x?

vichka [17]

Answer:

$x = 5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}$

Step-by-step explanation:

We need to solve the quadratic equation

6 = x^2 -10x

Rearranging we get,

x^2-10x-6=0

Using quadratic formula to solve the quadratic equation

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

a= 1, b =-10 and c=6

Putting values in the quadratic formula

$x=\frac{-(-10)\pm\sqrt{(-10)^2-4(1)(-6)}}{2(1)}\\x=\frac{10\pm\sqrt{100+24}}{2}\\x=\frac{10\pm\sqrt{124}}{2}\\x=\frac{10\pm\sqrt{2*2*31}}{2}\\x=\frac{10\pm\sqrt{2^2*31}}{2}\\x=\frac{10\pm2\sqrt{31}}{2}\\x = 5\pm\sqrt{31}$

So, $x=5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}$

A rectangular soccer field is 120 ft long by 64 ft wide. What dimensions would a scale drawing of the soccer field be if the fie

timofeeve [1]

Answer:

Hence dimension on drawing= 12 in by 6.4 in

Step-by-step explanation:

Actual dimension of the soccer field is 120 ft by 64 ft

Scale during drawing = 1in to 10 ft

Hence dimension on drawing = 120/10 by 64/10 = 12 in by 6.4 in

the perimeter of the triangle shown to the right is 154 meters. find the lenght of each side. (4x)m (7x+2)m (7x+8)m

yaroslaw [1]

The first to find the length of each side, we have to find the value of x :
$(4x) + (7x + 2) + (7x+8) = 154$

$4x + 7x + 7x + 2+8 = 154$

$18x +10 = 154$

$18x = 154 - 10$

$18x = 144$

$x = \frac{144}{18}$

$\boxed{x=8}$

Solution First side :
 $(4x)m = (4 \cdot 8)m = 32\ m$ 

Solution Second Side :
 $(7x+2)m = (7(8)+2)m = 58\ m$ 

Solution Third Side :
 $(7x+8)m = (7(8)+8)m = 64\ m$

Which figure shows a reflection of pre-image DEFG over the x-axis?

Sergio [31]

The image that shows the reflection of DFEG over the x-axis is the FIRST option. The x-axis is the mirror line. The distance from the mirror line to the reflected shape equals to the distance from the original image to the mirror line.
