5x +3 4x - 1 6x – 1 9x 5x + 4 12x Perimeter Review 9x + 4x – 1 + 5x + 4 18x + 3 6x – 1 + 5x + 3 +12x 23x + 2 Write an expression in simplest form that will solve for the perimeter of each of the triangles.
Solve the Equation 8z –4 –10z = –20 – 2z –4 = –20 +4 = +4 – 2z = –16 – 2 – 2 z = 8
CHECK Rewrite the problem. Everywhere you see a z, put in an 8 8z - 10z - 4 = - 20 8 (8) - 10 (8) - 4 = -20 64 - 80 - 4 = - 20 - 16 - 4 = - 20 - 20 = - 20
