me pueden ayudar si entienden porfavor

Answer 1

Respuesta:

$a)4 \times (3 + 7) = 4 \times 3 + 4 \times 7 = 12 + 28 = 40$

$b)3 \times (10 + 6) = 3 \times 10 + 3 \times 6 = 30 + 18 = 48$

$c)7 \times (9 - 3) = 7 \times 9 - 7 \times 3 = 63 - 21 = 42$

$d)5 \times (12 - 4) = 5 \times 12 - 5 \times 4 = 60 - 20 = 40$
