Sail with the equation by completing the square x^2+8x=-3

maxonik [38]

Answer:

The solutions are $x=-4(+/-)\sqrt{13}$

Step-by-step explanation:

we have

$x^{2} +8x=-3$

Complete the square. Remember to balance the equation by adding the same constants to each side

$x^{2} +8x+16=-3+16$

$x^{2} +8x+16=13$

Rewrite as perfect squares

$(x+4)^{2}=13$

square root both sides

$x+4=(+/-)\sqrt{13}$

$x=-4(+/-)\sqrt{13}$

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

jekas [21]

The sum of the interior angles in the polygon whose side is 10 is $1440^{0}$

<h3>What is sum of interior angle of polygon ?</h3>

The sum of the interior angles in a regular polygon is given by the formula 180(n – 2), where n is the number of sides in the polygon.

As, The formula for calculating the sum of interior angles is ( n − 2 ) × $180^{0}$

S0, n=10

Then, sum of interior angle be = (n-2) x 180

= (10-2) x 180

= 8 x 180

$= 1440^{0}$

Thus, the sum of the interior angles in the polygon is $1440^{0}$
