Complete questions 6,7,8.

Step-by-step explanation:

Prime factors of :

• 80 = 2 × 2 × 2 × 2 × 5

• x² = x × x

• y = y

• 80x²y = 2 × 2 × 2 × 2 × 5 × x × x × y

Prime factors of :

• 56 = 2 × 2 × 2 × 7

• x³ = x × x × x

• y² = y × y × y

• 56x³y² = 2 × 2 × 2 × 7 × x × x × x × y × y

Prime factors of :

• 81 = 3 × 3 × 3 × 3

• x = x

• y² = y × y

#CMIIW ^^

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.

step-by-step explanation:

mean or average is 40.6
