1/8 of all=mystery
mystery=3

'of' means multiply
therefor
1/8 times all=3
multiply both sides by 8/1 to clear fracion
all=24

The equation $a^7xy-a^6y-a^5x=a^4(b^4-1)$ is equivalent to the equation $(a^mx-a^n)(a^py-a^2)=a^4b^4$ for some integers $m$, $n$

Ksivusya [100]

Let simplify the equations $a^7xy-a^6y-a^5x=a^4(b^4-1)$ and $(a^mx-a^n)(a^py-a^2)=a^4b^4$ :

1) $a^7xy-a^6y-a^5x+a^4=a^4b^4$

and

2) $a^{m+p}xy-a^{n+p}y-a^{m+2}x+a^{n+2}=a^4b^4$ .

Equate the coefficients:

 $xy: m+p=7 \\ y: n+p=6 \\ x: m+2=5 \\ 1: n+2=4$ .
Then $n=2 \\ p=4 \\ m=3$ and mnp=24.

the area A of a sector circle is given by A= ... idk how to write that so look at the image please lol

Pavel [41]

A=πr^2s/360 multiply both sides by 360

360A=sπr^2 divide both sides by πr^2

s=360A/(πr^2)
