a. 2 pi
b. 6.875
c. 6.
d. both a and c
e. all of the above

D. Both a and c

Step-by-step explanation:

Irrational numbers can not written in a fraction form

For A, since pi is a irrational number, 2 time of it still make it irrational

For B,  6.875 could be written in fraction as 6785/1000, a rational number

For C, the number can not expressed in a fraction form because it goes on indefinite, an irrational number.

answer: ur v dumb

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
