[tex]c+d=\frac{3}{4} x+19,25+19,25x+\frac{3}{4}=0,75x+19,25+19,25x+0,75=20x+20\\ 20*0,5+20=10+20=30\\(c+d)*(c+d)=30*30=900[/tex]Odpowiedź:
Szczegółowe wyjaśnienie:
Odpowiedź:
c= 3/4x+19,25 ->c=3/4*0,5+19,25=0,75*0,5+19,25=0,375+19,25=19,625
d=19,25x +3/4 ->19,25*0,5+0,75=9,625+0,75=10,375
(c+d)*(c+d)=(c+d)^2
(19,625+10,325)^2=30^2=900
