answer any of these 1. In the straightaways each lane is a rectangle what is the area and perimetee of each lane in the straightaways? What is the area and perimeter of the larger rectangle made up of the six lanes in one of the straightaways? 2. What is the area of the inner field? What is the area of the entire track (the inner field and the lanes)? Use 3.13 for (pi) and round your answer to the nearest hundredth. 3. What is the perimeter of the entire track? Use 3.14 for (pi) and round your answer to the nearest hundredth. Explain your reasoning. ​

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.

x-3y=4

step-by-step e

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
