Which sentence is true about equilateral triangle . A. only 2 sides are the same length

B. only 2 angels have the same measure

C. Each side is a different length

D. All sides are the same length

E. Each angel has a different measure

Actually Welcome to the concept of Equilateral triangles.

Since, from the name itself, equilateral triangles have all sides and angles equal.

Hence the correct answer is

==> D. All sides are the same length.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
