Can 8 in, 10 in, 6 in be a right triangle

Lena reflected this figure across the x-axis. she writes the vertices of the image as a'(−2, 8), b'(−5, 6), c'(−8, 8), d'(−4, 2).

Solve x+3y=6 and 4x-6y=6 by elimination . show work !

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3
