1. True
Explanation: (12+8) = 20 . . . 20/10 = 2 and 12/6 = 2
2. False
Explanation: 3(-6) = -18+5 = -13 . . . 26-3 = 23
3. I'm not quite sure about this one, but here's what I got:
Explanation: 8x-3 /8 = x=3/8 . . . 10x-1 /10 = x=-1/10
Also with the "open" option I've never heard of that option before so I'm not sure about that answer choice.
Answer:
B
Step-by-step explanation:
I used the quadratic formula
R= c/2pi
Swap the sides of the equation
Divide both sides of the equation by 2pi
Write the solution in parametric form
It’s B
Cause if 400+80 is 480+9=489+0.6=489.6+0.05 and the final results it’s 489.65

So parallel is ll
and perpendicular is T
