Question 2
Which of these expressions is equal to 4m + 8m?

12 m

Step-by-step explanation:

Given the expression : 8m + 4m

The numbers 8m and 4m are bound by the addition operator.

When using the addition operator, the Coefficient are are the values added for like terms.

Since both values given can be like terms based on 'm', the Coefficient of m in each vlaue is added ;

Hence, we have ;

8m + 4m = 12m

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.
