new per:2560
Step-by-step explanation:
first perimeter u get it by adding all the sides and since its a square then all the sides are equal so u can just do
320*4 which is equal to 1280
and by doubling the sides u can just double it in the old equation meaning
(320*2)*4

Answer:
x= 226/3 or 75.33333333333333333333333333333
Step-by-step explanation:
14y+82=6x-20
y=25
Sub y=25 into 14y+82=6x-20
14y+82=6x-20
14(25)+82=6x-20
Calculate as follows:
14(25)+82=6x-20
350+82=6x-20
432=6x-20
Add twenty to both sides:
432+20=6x-20+20
452=6x-0
452=6x
Divide both sides by 6
452=6x
452/6=6x/6
452/6=x
x= 226/3 or 75.33333333333333333333333333333
