ON TIMER ONLY 2 MIN LEFT PLEASE HELP!!!!
When asked to find the distance between the complex points 3 + 8i and 7 + 6i, Zach showed the work below.
He asked his friend Zöe to find his mistake, and she correctly told him that he should have
A:subtracted the real and imaginary portions of the point in the same order.
B:left the i out of the computations when finding distance in the complex plane.
C:remembered that –4 squared should be –16, not 16.
D:simplified root12 to 3root2, not to 2root3
