(2x^2)^3 was für ein Ergebnis

${\color{blue}(2x^2)^3=8x^6}$  !

The length of a rectangular garden...

That was today at about 8 o'clock {nl} by heureka and me.

asinus :- )    !

wie rechne ich mit x ungleich 0,5

Ist die Variable x in einem Term oder einer Gleichung enthalten, darf x jeden Wert, natürlich, reell, komplex, irrational, transzendent, positiv, negativ und so weiter, annehmen,

nur nicht den Wert 0,5.  !

The length of a rectangular garden is double it's width. The area of the garden is 162 m squared. If the garden wishes to construct a fence diagonally across the garden, how much fencing(in meters) will be required? round your answer to the nearest meter

$A=l\times w= 2w\times w =162\ m^2$

 $2w^2=162m^2$

$w=\sqrt \frac{162\ m^2}{2} = 9m$

$l=2w=2\times 9m = 18m$

$f = \sqrt {w^{2}+l^2}$ = $\sqrt{(9m)^2+(18m)^2}$  

$f=\sqrt{405m^2}$  = $20.125\ m$

${\color{blue}21\ m \ fencing \ will \ be \ required.}$

17/20>3/5=

${\color{blue}\frac{17}{20}> \frac{3}{5} = 0.85>0.6 \ \ and \ that \ is \ correct.}$

What is 100 5/8 divided by 14 3/8

$100\frac{5}{8}: 14\frac{3}{8}$ = $\frac{805}{8}: \frac{115}{8}$

= $\frac{805}{8}\times \frac{8}{115}$ = $\frac{805}{115}$

= 7     !

how do you change this equation (5x+4y+8) into an equation that I can use for slopes?

There is no equation.   

5 5/12times 3 1/3

$5\frac{5}{12}\times3\frac{1}{3}$= $\frac{65}{12}\times\frac{10}{3}$ = $\frac{650}{36}$ = ${\color{blue}18\frac{1}{18}}$

m=((x+nx+4)/2) solve for x

$m=\frac{x+nx+4}{2}$ 

$2m=x+nx+4$

$2m-4= x\times(n+1)$

${\color{blue}x= \frac{2m-4}{n+1}}$

What is 2/3 × 3/7

${\color{blue}\frac{2}{3}\times\frac{3}{7}=\frac{2\times3}{3\times7}=\frac{2}{7}}$      !
