It costs more a month, but Webpages load faster with a (6)high-speed connection, I can upload and download files quicker. I usually (7)check my email first and write a few messages to family and friends.

\(x^2-10x+25=0\)

\(\Leftrightarrow\left(x-5\right)^2=0\)

\(\Leftrightarrow x-5=0\)

Vậy phương trình trên có tập nghiệm S=\(\left\{5\right\}\)

tính từ của slowly là slow

danh từ của construct thì mik chịu

\(\left|2014-x\right|=\left|x-2014\right|\)

Ta có \(\left|2014-x\right|=\left|-\left(2014-x\right)\right|\)

thay 2014-x= C ta được;\(\left|C\right|=\left|-C\right|\)(luôn đúng)=>\(\left|2014-x\right|=\left|x-2014\right|\)
