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