Hello!
An equilateral triangle has all three sides the same length
To find the perimeter you add the sides
4.6 + 4.6 + 4.6 = 13.8
The answer is 13.8mm
Hope this helps!
SSS - the side they're sharing is also congruent so if you just add in the other congruent sides you get SSS
What you want to do, is isolate the y by itself to rewrite the equation as y=mx+b. So when you move the 5x over the equation looks like this -6y=-5x+30. Then you divide the -5x+30 by -6 to isolate the y. Thus making the equation y=5/6x-5. And since there is only one answer with the y-intercept as (0,-5); The answer is A.
