Simplify the expression (3a4)(−6a3) . Show your work and justify each step.

I'm going to assume the 4 and 3 are exponents and the expression is .

The first step is to separate the coefficients of 3 and -6 from the variables and to multiply those as normal:

As for the variables, you want to recognize that means and means , so

In total, there are 7 a's being multiplied, so

Putting this all together, we have:

because 1.2 isnt half of 6 duh

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
