(2x^5 y^4) (-8x^-3 y^2) simplify

Answer in pic attached remember if multiplying x^2 and x^4 just add the powers x^6. But remember it only works with the same variable. You can't add if it's between x and y or any other different variable

so what is the question

step-by-step explanation:

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.
