$\frac{6x}{x^2+6x}=\frac{6x}{x(x+6)}=\frac{6}{x+6}$ -------- $\frac{a^2}{a-3}-\frac{9}{a-3}=\frac{a^2-9}{a-3}=\\\\\frac{a^2-3^2}{a-3}=\\\\\frac{(a-3)(a+3)}{a-3}=a+3$

She is а housewife. My younger sister is а pupil. She is in the seventh form. My grandmother lives with us.She doesn't work. She is а pensioner. I love my family. We are all friends and we love each other.
I have one aunt and two uncles. Their children are my cousins. We live in a big flat in а new house. There are four rooms in our flat: а living room, а study, а kitchen, а bathroom and two bedrooms. We have all modern conveniences: gas, hot water, running water, electricity and telephone.
I have my duties about the house. I must go shopping. I help my Mother to clean the rooms. It' s not difficult for me. I like our home to be clean and tidy.
I am а student of the college now. We have many good teachers at our college. I try to be а good pupil and I do well in а11 subjects. But my favourite subject is English.
I spend much time on it. 1 like reading. I like detective stories but I prefer to read historical novels or modern writers. I have many friends. Many of them are my classmates. We spend much time together, go for а walk, talk about lessons, music and discuss our problems.
I like to listen to modern music, but sometimes I like to listen to some classical music. My favourite composer is Tchaikovsky. I haven't much time to watch TV but sometimes I spend an hour or two watching an interesting film or a news programme. In the evening I often read newspapers or an interesting book. I like fresh air and exercises, but I have not much time to go in for sports. Перевод:)
