Length ≈ 31cm

Width ≈ 10cm

Step-by-step explanation:

$Let -the-length-be : x\\Let-the-width-be :y\\\\According- to- the- question ; \\x = 3(y)\\x=3y ---------(1)\\2(l+w)=82\\2(x+y)=82\\2x+2y =82 --------(2)\\Substitute- the - given- value- for ; x -in - equation---(1) into -equation (2)\\2(3y)+2y =82\\6y+2y=82\\8y =82\\\frac{8y}{8} =\frac{82}{8} \\y = 10.25\\\\Substitute 10.25 -for ;y -in -eq 1\\x=3y ---------(1)\\x = 3(10.25)\\x = 30.75$

CHECK

$Length =31\\Width = 10\\P = ?\\P= 2(l+w)\\P = 2(31+10)\\P = 2(41)\\P= 82cm$

Factor Completely<br><br> 2(4x-1)^2(x+5)+6(4x-1)^3(x+5)

SashulF [63]

Hello,
Let's factor:

2(4x-1)² * (x+5) + 6(4x-1)³ * (x+5)
=2(4x-1)²(x+5)*[1+3(4x-1)]
=2(4x-1)²(x+5)(12x-2)
=4(4x-1)²(x+5)(6x-1)
