The measures of three line segments are given in each set. Which set of line segments cannot form a triangle?

20.2 m, 20.4 m, 20.6 m

32.8 m, 48.2 m, 81.1 m

12.8 m, 25.7 m, 35.9 m

35.6 m, 49.9 m, 83.2 m

second option: 32.8 m, 48.2 m, 81.1 m  

Step-by-step explanation:

20.2 m + 20.4 m = 40.6 m.  which is bigger than 20.6 m. so yes  

32.8 m + 48.2 m = 81 m.  which is smaller than 81.1 m. so no  

12.8 m + 25.7 m = 38.5 m. which is bigger than 35.9 m. so yes  

35.6 m + 49.9 m = 85.5 m. which is bigger than 83.2 m. so yes

answer: l

step-by-step explanation:

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
