So you have 3, X&y in common so you have 3xy(3x + 4y) :)
D
A, B, C and E are linear equations ( equations of straight lines )
y = 2x² - 1 is a parabola → not linear → D
Answer:
arc ABC = 196°
arc DC = 360 - 196 - 70 = 94° (which looks out of proportion, but so does angle D)
Step-by-step explanation:
arc ABC = 2(∠D) = 2(98°) = 196°
To start this, try to place it all together.
(x)+(x+2)+(x+4)=36
Then you start to combine so that it looks like this:
3x+6=36
I believe that is one of the choices. Do you need more explanation?
