Answer:
Per2 = 102.727 dm
Per1 = 123.272 dm
Step-by-step explanation:
We know that the area of similar triangles are related to the square of their perimeters.
This means that
(Per1^2)/(Per2^2) = Area1 / Area2
If we take the square root of the previous equation
(Per1)/(Per2) = 
(Per1)/(Per2) = 
(Per1)/(Per2) = 1.2
We also know that
Per1 + Per2 = 226 dm
So,
1.2*Per2 + Per2 = 226 dm
2.2*Per2 = 226 dm
Per2 = 102.727 dm
Per1 = 1.2*Per2 = 123.272 dm

Answer:
5x - (x/y) = 18 when x=4 and y=2
Step-by-step explanation:
5x - (x/y)
When x=4 and y=2
Substitute the value of x=4 and y=2 into the expression
5x - (x/y)
5(4) - (4/2)
Multiply 5 by 4 and divide 4 by 2
=20 - 2
Subtract 2 from 20
=18
5x - (x/y) = 18 when x=4 and y=2
Well, breaking it down, you're going to do 780/8, in two/three steps.
First, you'll do 78/8, which is 9. 78- (8*9) is now
78-72 = 7.
Then, we're going to take the 0 and put that at the end of 7, making it 70
so 70/8 is 8, with 6 left over.
Now we smoosh these numbers together to get 96 remainder 6
