The standard form for the equation of a circle is :

(x−h)^2+(y−k)^2=r2
where handk are the x and y coordinates of the center of the circle and r is the radius.
Subtituting h=4, k=0 and r=4 gives :

(x-4)^2+(y)^2=16

Solve the following equations for x<br><br> 13−(2x+2)=2(x+2)+3x

Montano1993 [528]

Answer:

x = 7

Step-by-step explanation:

Distribute the 2 on the right and the -1 on the left: 13 - 2x - 2 = 2x + 4 + 3x

Combine like terms on each side of the equation: 11 - 2x = 5x + 4

Add 2x to both sides, and subtract 4 from each side: 7 = 7x

Divide both sides by 7: x = 7

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 $1440^{0}$
