|5| - 4(3² - 2)

<u>Simplifying in steps:</u>

5 - 4(9 - 2) =
5 - 4(7) =
5 - 28 =
-23

Correct choice is B

$\\ \sf\longmapsto |5|-4(3^2-2)$

$\\ \sf\longmapsto 5-4(9-2)$

$\\ \sf\longmapsto 5-4(7)$

$\\ \sf\longmapsto 5-28$

$\\ \sf\longmapsto -23$

Answer:

Step-by-step explanation:

$\frac{12x}{2x-3x-10}-\frac{x}{x-5}=\frac{12x}{-x-10}-\frac{x}{x-5}\\\\=\frac{12x}{-(x+10)}-\frac{x}{x-5}\\\\=\frac{-12x}{x+10}-\frac{x}{x-5}\\\\=\frac{-12x*(x-5)}{(x+10)*(x-5)}-\frac{x*(x+10)}{(x-5(x+10)}\\\\=\frac{-12x*x-5*(-12x)}{(x+10)(x-5)}-\frac{x*x+x*10}{(x-5)(x+10)}\\\\=\frac{-12x^{2}+60x}{(x+10)(x-5)}-\frac{x^{2}+10x}{(x-5)(x+10)}\\\\=\frac{-12x^{2}+60x-(x^{2}+10x)}{(x+10)(x-5)}\\\\=\frac{-12x^{2} + 60x - x^{2}-10x}{x^{2}+5x-50}\\\\=\frac{-13x^{2}+50x}{x^{2}+5x-50}$

How do I do this ? I don’t understand logarithm

ale4655 [162]

Hello from MrBillDoesMath!

Answer:

x = 19

Discussion:

Both sides are logarithms to the same base, namely 20 , which implies the expressions in x (what we are taking logarithms of) must be equal. So we need to solve

4x - 10 = 3x + 9 => subtract 3x from both sides

4x-3x - 10 = 9 => add 10 to both sides

x = 9 + 10 = 19

Thank you,

MrB
