Ex 2 va rog frumos va rog frumos

Answer 1

triunghi verde = 8×3+8+3×3+2×3=24+8+9+6=30+17=47;

romb verde = 28:4+4:4=7+1=8;

patrat verde = 9×9-6×6+42:6=81-36+7=52;

patrat alb = (50 - 8):(12-5)=42:7=6;

cerc alb = (17-9)×(27:3)=8×9=72;

triunghi alb = 81:9+63:7-11=9+9-11=7;

Pretul = 72:8+47+52+6×7=9+99+42=150 de lei
