cine ma ajuta la ex 2 va rog​

Answer 1

Răspuns:

Explicație pas cu pas:

8 × 3 + 8 + 3 × 3 + 2 × 3 = 47 → triunghiul ,,plin"

= 24 + 8 + 9 + 6 =

= 32 + 9 + 6 =

= 41 + 6 =

= 47

_______________________

28 : 4 + 4 : 4 = 7 + 1 = 8 → romb

________________________

9 × 9 - 6 × 6 + 42 : 6 = 81 - 36 + 7 = 45 + 7 = 52 → patrat ,,plin" (colorat)

______________________________________________________

( 50 - 8 ) : ( 12 - 5 ) = 42 : 7 = 6 → patrat ,,gol"

__________________________________

(17 - 9 ) × ( 27 : 3 ) = 8 × 9 = 72 → cerc

_____________________________

81 : 9 + 63 : 7 - 11 = 9 + 9 - 11 = 18 - 11 = 7  → Δ

_____________________________________

72 : 8 + 47 + 52 + 6 × 7 = 9 + 99 + 42 = 108 + 42 = 150
