What does the variable r represent in the equation 10r+4=8

The value of variable r in the equation is

Step-by-step explanation:

We need to find the value of variable r in the equation

Step 1: Write the equation

Step 2: Subtract 4 on both sides

Step 3: Divide both sides by 4

So, The value of variable r in the equation is

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.

answer: it's d
