Olá meu parça !!!
Vamos Calcular passo a passo;
[tex]Pergunta : [/tex]
1 - Quais os resultados das operações ?
a) 37+20-14+2-15
b)(-3) . (-4) +12-3
c)3 . (-4+x)
-----------------------------------------------------------------
[tex]Resposta:[/tex]
Calcule da seguinte forma !
A)
[tex]\textcolor{blue}{37 + 20 - 14 + 2 - 15}[/tex]
[tex]\textcolor{blue}{59 - 14 - 15}[/tex]
[tex]\textcolor{blue}{59 - 29}[/tex]
[tex]\large \: \red{\hookrightarrow \: {\boxed{\boxed{\mathrm{ \: \: \: 30 {}{} \frac{}{} {} \: \:}}}} \:\hookleftarrow} \: ✔[/tex]
-----------------------------------------------------------------
B)
[tex]\textcolor{blue}{ - 3 \times ( - 4) + 12 - 3}[/tex]
[tex]\textcolor{blue}{12 + 12 - 3} \: \boxed{{\textcolor{red}{ calcule \: a \: soma }}}[/tex]
[tex]\large \: \red{\hookrightarrow \: {\boxed{\boxed{\mathrm{ \: \: \: 21 {}{} \frac{}{} {} \: \:}}}} \:\hookleftarrow} \: ✔[/tex]
-----------------------------------------------------------------
C)
[tex]\textcolor{blue}{3 \: ( - 4 + x)}[/tex]
[tex]\textcolor{blue}{3 \: (x - 4)} \: \boxed{{\textcolor{red}{ fatorando}}}[/tex]
[tex]\large \: \red{\hookrightarrow \: {\boxed{\boxed{\mathrm{ \: \: \: 3 \: ( - 4+x){}{} \frac{}{} {} \: \:}}}} \:\hookleftarrow} \: ✔[/tex]
[tex]\large \: \red{\hookrightarrow \: {\boxed{\boxed{\mathrm{ \: \: \: 3 \: (x-4){}{} \frac{}{} {} \: \:}}}} \:\hookleftarrow} \: ✔[/tex]
[tex]\large \: \red{\hookrightarrow \: {\boxed{\boxed{\mathrm{ \: \: \: 12 \: \:{}{} \frac{}{} {} \: \:}}}} \:\hookleftarrow} \: ✔[/tex]
-----------------------------------------------------------------
[tex]\boxed{{\textcolor{red}{ Bons \: Estudos \: !!!}}}[/tex]
