Answer:
b. 80
Step-by-step explanation:
The mean is all of them added together divided by the number, so multiple the mean by the number of sides, 3, and that's the perimeter. 18 x 3 = 54
I believe the answer is 35 degrees, or A.
Y=1/2x+8
Step by step explanation This is how I got the answer to your question and I gave you the solution I hope this helps you out
Perpendicular lines, slope is opposite and reciprocal
so slope of new line = - 4
passes through (-2, -6) in point-slope form
y + 6 = -4(x + 2)
Answer is C. y + 6 = -4 (x + 2)
