Question

The value of the expression (2x^2)/(x) + x(100-15x) when x = 5 is

Answer 1

45 is the answer for the expression

Answer 2

Answer:

$\dfrac{2x^2}{x} + x(100-15x)$ at x=5

135

Step-by-step explanation:

Given: The expression $\dfrac{2x^2}{x} + x(100-15x)$

This is rational expression of variable x.

Put x=5 into the expression and then simplify

$\Rightarrow \dfrac{2\cdot 5^2}{5} + 5(100-15\cdot 5)$

$\Rightarrow 2\cdot 5 + 5(100-75)$

$\Rightarrow 2\cdot 5 + 5\cdot 25)$

$\Rightarrow 10+125$         (Addition of two integer)

$\Rightarrow 135$

Hence, The value of given expression is 135
