--------------------------------------------------------------
Find x :
--------------------------------------------------------------
Sum of adjacent angles on a straight line is 180.

∠ABY + ∠YBC = 180
x + 25 + 2x + 50 = 180
3x + 75 = 180
3x = 105
x = 35

--------------------------------------------------------------
Check if AC is parallel to DF :
--------------------------------------------------------------
If AC is parallel to DF, 
∠YBC = ∠BEF (Corresponding angles)

∠YBC = 2x + 50 = 2(35) + 50 = 120
∠BEF = 5x - 55 = 5(35) - 55 = 120

Since ∠YBC = ∠BEF, AC and DF are parallel.

---------------------------------------------------------------------------------------------
Answer: Since ∠YBC = ∠BEF, AC and DF are parallel.

The image below is a triangle drawn inside a circle with center O:
dsp73
The area of a circle is r^2pi and 2r = diameter. Thus r=diameter/2
r=6/2= 3 inches so the expression is 3^2*3.14 so I believe it's B

I'm not sure if this is a trick question but 1/2 because there are 2 options(yellow or blue) and one desired outcome(yellow)

Given that -5 is a zero of the function f(x) = x^3 + x^2 - 14x + 30 find the remaining zeros
vampirchik [111]
Since the factors are (x+5)(x^2-4x+6)

the zeros would be 2+i√2 and 2−i√2
