1km/h = \(\frac{1000m}{3600s}\) = \(\frac{5}{18}\)(m/s)

Muốn đổi km/h sang m/s ta lấy số km/h nhân với \(\frac{5}{18}\)

3km/h = 3 x \(\frac{5}{18}\)m/s = \(\frac56\)m/s

Ta có: \(2y^2\left(x-2\right)-4xy+8y\)

\(=2y^2\left(x-2\right)-4y\left(x-2\right)\)

\(=\left(x-2\right)\left(2y^2-4y\right)=2y\left(y-2\right)\left(x-2\right)\)

My House

My house is small but cozy. It has a living room, two bedrooms, a kitchen, and a bathroom. The walls are painted light blue, making the space feel fresh and peaceful. Outside, there is a small garden where my mother grows flowers and vegetables.

I love my bedroom the most because it has a bookshelf full of my favorite stories and a soft bed. Every morning, sunlight shines through the window, warming the room. My house may not be big, but it is filled with love and laughter. It is my favorite place in the world.

Hi Linh,

I'm on holiday in Da Nang with my family. I'm sitting on the beach right now. The sun is shining and the sea is really blue. My mum is reading a book under an umbrella, and my dad is taking photos of the waves. My little brother is building a sandcastle — it's so cute!

Where are you at the moment?

Email me soon.

Hi [Friend’s Name],

I’m on holiday in Da Nang – a dream place with blue sea, white sand, and golden sunshine! I’m having an amazing time with my family. My mum is relaxing on a deck chair, reading her favorite book, while my dad is fishing by the beach nearby. My little sister is building a cool sandcastle right now!

Where are you at the moment? How’s your holiday going?

Email me soon and tell me all about it!
