Giải:

Ta có:

14km3m=14km+0,003km=14,003km

Đáp số : 14,003km

Chọn D

( x + 5 ) + ( x + 10 ) + ( x + 15 ) + ... + ( x + 2015 ) = 408239

( x + x + x + ... + x ) + ( 5 + 10 + 15 + ... + 2015 ) = 408239

Số số hạng là : ( 2015 - 5 ) : 5 + 1 = 403

Tổng là : ( 2015 + 5 ) x 403 : 2 = 407030

x * 403 + 407030 = 408239

x * 403 = 1209

x = 1209 : 403

x = 3

 Vậy x = 3

3 hình bn nha
