Answer:

-57

Step-by-step explanation:

$log \frac{ {c}^{7} }{ {a}^{6} {b}^{2} } \\ \\ = log {c}^{7} - log( {a}^{6} {b}^{2} ) \\ \\ = log {c}^{7} - (log {a}^{6} + log{b}^{2} )\\ \\ = 7 \: log {c} - (6 \: log {a}+ 2 \: log{b})\\ \\ = 7 \:( - 9) - [6 \: ( - 5)+ 2 \: (12)] \\ \\ = - 63 - [ - 30 + 24] \\ \\ = - 63 - [- 6] \\ \\ = - 63 + 6 \\ \\ = - 57$

CORRECT ANSWER FOR BRAINLIEST

Alchen [17]

$\bf \cfrac{x^2-x-6}{4x^3}\cdot \cfrac{2x^2+2x}{x^2+5x+6}\implies \cfrac{(x-3)\underline{(x+2)}}{\underline{2x}(2x^2)}\cdot \cfrac{\underline{2x}(x+1)}{(x+3)\underline{(x+2)}}
\\\\\\
\cfrac{x-3}{2x^2}\cdot \cfrac{x+1}{x+3}\implies \cfrac{\stackrel{FOIL}{x^2-2x-3}}{2x^3+6x^2}$

Answer:

Extracting out that inner right angle.

Hypotenuse = 8

Height = h

Adjacent :

$= \frac{10}{5} = 2$

Height, h :

${ \tt{h = \sqrt{ {8}^{2} - {5}^{2} } }} \\ { \tt{h = \sqrt{64 - 25} }} \\ { \tt{h = \sqrt{39} }} \\ the \: height \: is \: { \boxed{6.2}} \: units$

How do you reduce 75/100?

Anestetic [448]

Find the greatest common factor and then divide each number by it.

in this case the gcf for 75 and 100 is 25.

75 divided by 25 = 3
100 divided by 25 = 4

so 75/100 simplified = 3/4
