The triangle below has a total perimeter of 450 cm.

(picture of a triangle with sides 128 and 150. third side unknown)

write an equation and solve it to find the length of the longest side of the triangle.

128x + 150 = 450; x = 2.34 cm

x + 278 = 450; x = 172 cm

2x + 278 = 450; x = 86 cm

150x + 128 = 450; x = 2.15 cm
