Answer:
1,726 cm
Step-by-step explanation:
it boils down to this equation:
2(19×29)+2(19×6.4)+2(29×6.5)
bc if you look closely, it's just each side twice (hope that makes sense)
then you work down from there
2(551)+2(123.5)+2(188.5)
1,102+259+337
1,726
Answer: 1 1/3 packs of treats
Step-by-step explanation:

Answer:
x = 12 , y = 10
Step-by-step explanation:
Let x , y are two numbers.
x > y
1 ) Three times the greater is 18 times their
difference
3x = 18( x - y )
x = 6( x - y )
x = 6x - 6y
6y = 5x
y = 5x/6 ——-( 1 )
2 ) 4 times the smaller is 4 less than twice
the sum of the two
4y + 4 = 2 ( x + y )
2y + 2 = x + y
y = x -2 ——( 2 )
From ( 1 ) and ( 2 ) ,
5x/6 = x -2
( 5x /6 ) - x = -2
( 5x - 6x ) /6 = -2
-x = -12
x = 12
Put x = 12 in equation ( 2 ) , we get
y = 12 - 2
y = 10
Therefore ,
x = 12 , y = 10
