What are the solutions of x2 - 2x +17 = 0 ?

a. x = 2i or x = -2i
b. x = 1+ 4i or x = 1 -4i
c. x= 4i or x = -4i
d. x = 1+2i or x = 1 - 2i

c-   36

taxicab circle radius 9 has 4(9) = 36 points

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
