Answer:
135
Step-by-step explanation:
The given expression is
[tex] \frac{2 {x}^{2} }{x} +x(100 - 15x)[/tex]
From the question, x=5
So,by substitution,we obtain
[tex] =\frac{2({5}^{2})}{5} +5(100 - 15(5))[/tex]
[tex] =\frac{2(25)}{5} +5(100 - 75))[/tex]
[tex] =2(5)+5(25)[/tex]
[tex] = 10+125[/tex]
[tex] = 135[/tex]
Hence the answer is 135
