What is the solution to the equation 2 (x-3) ^2 =13 help help ASAP !

olganol [36]

Answer:

3+sqrt(13/2)

3-sqrt(13/2)

Step-by-step explanation:

2 (x-3) ^2 =13

Divide each side by 2

2/2 (x-3) ^2 =13/2

(x-3) ^2 =13/2

Take the square root of each side

sqrt((x-3) ^2) =±sqrt(13/2)

x-3 = ±sqrt(13/2)

Add 3 to each side

x-3+3 = 3±sqrt(13/2)

x = 3±sqrt(13/2)

Find the perimeter and area of the polygon shown below. The polygon is a trapezoid made up of a rectangle and a right triangle.

algol13

Since, the polygon is a trapezoid made up of a rectangle and a right triangle. Therefore, according to the question, the figure of the polygon is attached.

Since, perimeter is the total length of the outer boundary of the figure. Therefore,

Perimeter of the polygon is $=AB+BE+ED+DC+CA$

$=18+17+8+18+15$

$=76 \ ft$

Area of the polygon = Area of Rectangle + Area of Triangle

$=[(18) \times (15)] + [(\frac{1}{2}) \times (8) \times (15)]$

$=270 + [(\frac{8}{2}) \times (15)]$

$=270 + [4 \times (15)]$

$=270 + 60$

$=330 \ {ft}^{2}$
