Delicious77 [7]

The easiest way it to solve it.
${x}^{2} + 5x + 2 = 0$
You have
$\rho = 25 - 4 \times 1 \times 2 = 17$
Thus
$x = \frac{ - 5 \pm \sqrt{17} }{2}$

Answer:

$\sqrt{h^2 + k^2}$

Step-by-step explanation:

Point O has coordinates (0, 0)
B has coordinates (h, k)
C has coordinates (h, 0)

<u>Use the distance formula to find the length of OB:</u>

OB = $\sqrt{(h-0)^2 + (k-0)^2}$ = $\sqrt{h^2 + k^2}$

Solve the equation. 8 – 2x = –8x + 14

goldenfox [79]

Answer:

$x=1$

Step-by-step explanation:

We are asked to solve the given equation: $8-2x=-8x+14$ .

To solve this equation we will combine like terms by moving all the terms containing x to the left hand side of equation and terms without x to right hand side of equation.

Let us add 8x to both sides of our equation.

$8-2x+8x=-8x+8x+14$

$8-2x+8x=14$

$8+6x=14$

Let us subtract 8 from both sides of our equation.

$8-8+6x=14-8$

$6x=14-8$

$6x=6$

Upon dividing both sides of our equation by 6 we will get,

$\frac{6x}{6}=\frac{6}{6}$

$x=\frac{6}{6}$

$x=1$

Therefore, the value of x equals 1 will satisfy our given equation.
