Solve for z. 5z − 6 − 34 = zz − 6

Step-by-step explanation:

5z-6-34=z-6

combine like terms (-6-34)

5z-40=z-6

subtract z on both sides

5z-z-40=-6

4z-40=-6

add -40 on both sides

4z=34

divide both sides by 4

z=

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
