Simplify the algebraic expression:

5 + 3(2y - 4) - 11y

5 + 6 − 1 2 − 1 1 -11y 5+6y−12−11y − 7 + 6 − 1 1

− 7 + 6 − 1 1  −7+6y−11y − 7 − 5

− 7 − 5 −7−5y − 5 − 7

Solution: −5−7

-5y -7

Step-by-step explanation:

expand: 3(2y-4):   6y-12 = 5+6y-12-11y        

simplify: 5+6y -12-11y:      -5y-7

-5y-7

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.
