x=7/√2
times (√2)/(√2)
(7√2)/2
3.5√2

Answer:

135

Step-by-step explanation:

The given expression is

$\frac{2 {x}^{2} }{x} +x(100 - 15x)$

From the question, x=5

So,by substitution,we obtain

$=\frac{2({5}^{2})}{5} +5(100 - 15(5))$

$=\frac{2(25)}{5} +5(100 - 75))$

$=2(5)+5(25)$

$= 10+125$

$= 135$

Hence the answer is 135
