What is the solution to this equation 10x-15x+5=-45+20

nataly862011 [7]

Answer:

Step-by-step explanation:

$10x - 15x + 5 = - 45 + 20$

Collect like terms

$- 5x + 5 = - 45 + 20$

Calculate the sum

$- 5x + 5 = - 25$

Move constant to RHS and change its sign

$- 5x = - 25 - 5$

Calculate

$- 5x = - 30$

Divide both sides of the equation by -5

$\frac{ - 5x}{ - 5} = \frac{ - 30}{ - 5}$

Calculate

$x = 6$

Hope this helps...

Best regards!!

Please help me to solve this ∫ 1/(x + √x) dx

skad [1K]

Answer:

$\boxed{2ln (\sqrt{x} + 1 ) + c}$

Step-by-step explanation:

$\int\limits {\frac{1}{x + \sqrt{x} } } \, dx$

$= \int\limits {\frac{1}{\sqrt{x} (\sqrt{x} + 1 )} } \, dx$

$= \int\limits {\frac{2}{(\sqrt{x} + 1 )} } \, d(\sqrt{x} + 1 )$

$= 2ln (\sqrt{x} + 1 ) + c$
