Answer 1

6) (7×2)+(7×5)=14+35=49
(3×5)+(7×5)=15+35=50
49=50=(F)

(2×3)×8=6×8=48
4×10+4×2=40+8=48
48=48=(A)

7) 6×(2+8)=6×10=60
5×(4+5)=5×9=45

Answer 2

$(7 \times 2) + (7 \times 5) = (3 \times 5) + (7 \times 5) = 14 + 35 = 15 + 35 = 49 = 50 \: \: \: este \: fals\\ \\ (2 \times 3) \times 8 = 4 \times 10 + 4 \times 2 = 48 = 48 \: este \: adevarat$
