4 = 2*2
6 = 2*3
9 = 3*3
LCD = 2 * 3* 2 * 3 = 36
so the fractions are 3/4 * 9/9 = 27/36
5/6 = 30/36 and 5/9 = 20/36
First set up a proportion because they are similar triangles:
9/3x-20 = (72+9)/(56+3x-20)
9/3x-20 = 81/3x+36
9(3x+36) = 81(3x-20)
27x+324 = 243x-1620
1944 = 216x
x = 9

Answer:
The circumference is the distance around the circle, similar to the perimeter of a polygon.
Step-by-step explanation:
The term "circumference" is often used to refer to the once-around length of any circular or roughly-circular object. One can refer to the circumference of an ellipse or of one's head, for example.
The correct answer is: -18 .

9i * 2i = 18 i² .
________________________________________
" i " is an imaginary number equal to "√(-1) " .
" i² " = [√(-1)] ² = √(-1) * √(-1) = -1 .
________________________________________
18 * i² = 18 * -1 = -18 .
