quem responder é meu herói namoral! é pra hoje...

Answer 1

a)

$( - 5 + 0) \times ( - 4 - 7) \\ \\ - 5 \: ( - 4 - 7) \\ \\ - 5 \times ( - 11) \\ \\ = 55$

b)

$( + 1 + 4) \times ( - 6 - 7) \\ \\ 5 \times ( - 13) \\ \\ = - 65$

c)

$(7 - 2) \times (1 - 4) \\ \\ 5 \times ( - 3) \\ \\ = - 15$

d)

$( - 3 + 5) \times ( - 4 + 1) \\ \\ 2 \times ( - 3) \\ \\ = - 6$

e)

$(0 - 4) \times ( - 2 + 6) \\ \\ - 4( - 2 + 6) \\ \\ - 4 \times 4 \\ \\ = - 16$

f)

$( - 1 - 6) \times ( - 8 - 3) \\ \\ - 7 \times ( - 11) \\ \\ = 77$

espero ter ajudado

꧁Hello, how are you?꧂

• Bom... vamos lá, baby!

$a) \: \: ( - 5 + 0) \times ( - 4 - 7) \\ - 5( - 4 - 7) \\ - 5 \times ( - 11) \\ 5 \times 11 \\ {\red{55}}$

$b) \: ( + 1 + 4) \times ( - 6 - 7) \\ 5( - 6 - 7) \\ 5 \times ( - 13) \\ - (5 \times 13) \\ {\red{ - 65}}$

$c) \: \: ( + 7 - 2) \times ( + 1 - 4) \\ 5(1 - 4) \\ 5 \times ( - 3) \\ - (5 \times 3) \\ {\red{ - 15}}$

$d) \: \: ( - 3 + 5) \times ( - 4 + 1) \\ 2( - 4 + 1) \\ 2 \times ( - 3) \\ - (2 \times 3) \\ {\red{ - 6}}$

$e) \: \: (0 - 4) \times ( - 2 + 6) \\ - 4( - 2 + 6 - ) \\ - 4 \times 4 \\ - (4 \times 4) \\ {\red{ - 16}}$

$f) \: \: ( - 1 - 6) \times ( - 8 - 3) \\ - 7( - 8 - 3) \\ - 7 \times ( - 11) \\ 7 \times 11 \\ {\red{77}}$

${\red{Keep \: loving...}}$
