If e equals 0.6, what would 12e-6*3e=

Best not to mix "E" with "e."  Also, please note that "e" is a special number in Math, often used as the base of exponential functions, valued at approx. 2.718.

12e-6*3e could be factored:  12e - 6*3e = 6e(2 - 3) = -6e

If e=0.6, then -6e = -6(0.6) = -3.6

The distance from point a to point c across the coordinate plane is aproxamatly 8.94 rounded to the nearest hundredth. you use a^2 + b^2 =c^2
