Respuesta :
The answer is -25.8 because 5-10=-5, -5*5=-25, then you simplify fraction and add/subtract
Answer:
[tex]\frac{-129}{5}[/tex]
Step-by-step explanation:
We have been given an expression [tex]\frac{20}{-25}+x(x-10)[/tex]. We are asked to evaluate our given expression, when [tex]x=5[/tex].
To evaluate our given expression, we will substitute [tex]x=5[/tex] in our given expression as:
[tex]\frac{20}{-25}+5(5-10)[/tex]
[tex]-\frac{4}{5}+5(-5)[/tex]
[tex]-\frac{4}{5}-25[/tex]
Make a common denominator:
[tex]-\frac{4}{5}-\frac{5*25}{5}[/tex]
[tex]-\frac{4}{5}-\frac{125}{5}[/tex]
[tex]\frac{-4-125}{5}[/tex]
[tex]\frac{-129}{5}[/tex]
Therefore, the value of our given expression [tex]\frac{-129}{5}[/tex].
