2х(х-4)-(2х+5)(х-10)<2(3,5х+50)

Let's solve the inequality step by step:

2х(х - 4) - (2х + 5)(х - 10) < 2(3.5х + 50)

Expanding the brackets on both sides:

2х^2 - 8х - (2х^2 - 20х + 5х - 50) < 7х + 100

Simplifying:

2х^2 - 8х - 2х^2 + 20х - 5х + 50 < 7х + 100

Combine like terms:

7х + 50 < 7х + 100

Subtracting 7х from both sides:

50 < 100

This is a true statement, which means that the inequality holds for all values of x. In other words, there is no restriction on the values of x that satisfy the inequality.
