Sara has a roll of wire 600 cm long. She cuts 3 equal pieces from it. Each piece is 28.5 cm . What is the length of the remaining roll of wire?

b) \( \left(x^{3}+3 x^{2}-2 x-8\right):(x+2)= \)

3) \( \frac{x+5}{x-5}-\frac{x-1}{x+5}= \)

Sebuah campuran semen dan pasir dibuat dengan perbandingan \( 1: 4 \). Jika digunakan semen sebanyak 25 kg , berapa pasir yang dibutuhkan?
