Question

14 a va roog imi trebuie foarte urgent

Answer 1

[tex]\frac{AP}{PB}=\frac{2}{7}=\ \textgreater \ AP=\frac{2PB}{7}\\ AP+PB=AB\\ \frac{2PB}{7}+PB=135\\ 2PB+7PB=945\\ 9PB=945=\ \textgreater \ PB=105 cm\\ AP=\frac{2*105}{7}\\ AP=\frac{210}{7}=\ \textgreater \ AP=30 cm[/tex]

Answer 2

AB = 135 cm 
daca  AP / PB = 2 /7        
atunci  ( AP + PB )  / PB = ( 2 + 7 ) / 7 
AB  / PB = 9 / 7 
7 · AB = 9 · PB 
7 · 135  cm  = 9 ·PB 
PB = 945 cm : 9 = 105 cm 
AP = 135 cm - PB = 135 cm  -  105 cm  = 30 cm
