NELLA REALTA Il bagno Per pavimentare un bagno rettangolare sono necessarie 63 piastrelle quadrate il cui lato mi- sura 25 cm . Calcola la lunghezza del bagno, sa- pendo che è largo \( 1,75 \mathrm{~m} \). [ \( 2,25 \mathrm{~m}] \)

9. ABC is a triangle in which \( m \overline{\mathrm{BC}}=m \overline{\mathrm{CA}}=2 \mathrm{~m} \overline{\mathrm{AB}} \). Internal bisector of \( \angle A \) meets \( \overline{\mathrm{BC}} \) at D and \( \overline{\mathrm{DE}} \) is drawn parallel to \( \overline{\mathrm{CA}} \) meeting \( \overline{\mathrm{AB}} \) at E . Find \( m \overline{\mathrm{DE}}: \mathrm{m} \overline{\mathrm{AB}} \).

23. Find the equation of a line. Whoso intercepts on \( x \) and \( y \) axis are 4 and -6
