Find the length of the segment with the given endpoints.

(17.1, 3), (21.4, 3)

4.3

Step-by-step explanation:

Because the y-coordinate stays the same, only look at the x-axis. Subtract 17.1 - 21.4 to get your length

the correct answer is 45x

9×5=45 then add the x

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
