Mathematics
1 answer:
Andreyy892 years ago
3 0

Answer:

<u>The correct answer is B. {-2,4}</u>

Step-by-step explanation:

Let's solve for x, this way:

x + 4/4 = x /x -2

(x + 4) * ((x - 2) = 4 * x

x² - 2x + 4x -8 = 4x

x² - 2x + 4x -8 - 4x = 0

x² - 2x  -8 = 0

(x - 4) * (x +2) = 0

x - 4 = 0

x + 2 = 0

x₁ = 4

x₂ = - 2

<u>The correct answer is B. {-2,4}</u>

Answer:

11) x = 45

12) x = 30

Find the radius of a circle in which the central angle of (pie /4 ) radian determines a sector with an area of 86m^2
LenKa [72]
Area of sector  = 1/2 * r^2 * x   where r = radius and x = angle in radians

86 = 1/2 * r^2 * pi/4

r^2 = 2 * 86 * 4  / pi  =  219

r =  sqrt 219

= 14.80
