This figure is made up of a quadrilateral and a semicircle.

Arturiano [62]

Answer:

The correct option is B. The area of the figure is 40.4 units².

Step-by-step explanation:

The line AB divides the figure in two parts one is a rectangle and another is semicircle.

The distance formula is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The length of AB is

$AB=\sqrt{(2+3)^2+(4-2)^2}=\sqrt{25+4}=\sqrt{29}$

The length of AD is

$AD=\sqrt{(-1+3)^2+(-3-2)^2}=\sqrt{4+25}=\sqrt{29}$

Since AB=AD, therefore ABCD is a square. The area of the of square is

$A_1=a\times a=\sqrt{29}\times \sqrt{29} =29$

The area of square is 29 units².

The area of a semicircle is

$A_2=\frac{\pi}{2}r^2$

Since AB is the diameter of the semicircle, therefore the radius of the semicircle is

$r=\frac{d}{2}=\frac{\sqrt{29}}{2}$

The area of the semicircle is

$A_2=\frac{3.14}{2}(\frac{\sqrt{29}}{2})^2=40.3825$

The area of the figure is

$A=A_1+A_2=29+11.2825=40.3825\approx 40.4$

Therefore the area of the figure is 40.4 units². Option B is correct.

Solve for y. 2/(y+3)= 3/(3y+9)

AfilCa [17]

Answer:

y= -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators:

2/y +3 = 3/3y + 9

(3y+9) (y+3) (2/y+3) = (3y +9) (3/3y+9)

Simplify:

6 + 1 8 = 3 + 9

Subtract 18 from both sides of the equation:

6y +18 =3y +9

6y+18 -18 =3y +9 -18

Simplify Again:

6y +3y-9

Subtract 3y from both sides of the equation:

6y =3y -9

6y-3y = 3y -9 -3y

Answer:

y= -3
