​

Answer 1

Respuesta:

Explicación paso a paso:

a=15

b=-8

c=-20

d=-78

e=-144

f=280

g=+1

h=-15

i=-90

j=72

Answer 2

Respuesta:

a. (+3) (+5) = 15 f. (+40) (+7) = 280

b. (+8) (–1) = -8 g. (–1) (–1) = 1

c. (-5) (–4) = 20 h. (5) (–3) = -15

d. (–1) (+78) = -78 i. (9) (–10) = -90

e. (+12) (–12) = -144 j. –9 (–8) =-72
