8 0

Answer:

2x - xy = 0

Step-by-step explanation:

We need to solve the equations simultaneously to find the values of x and y:

x + y = 12

x - y = 8 - we need to add the equations together

2x = 20

x = 10

Then we substitute x into one of the equations to find y:

10 + y = 12

12 - 10 = y

y = 2

Now we substitute x and y into the final expression:

2(10) - 2(10)

20 - 20 = 0

Answer:

5/2

Step-by-step explanation:

... 75/12 = 25/4

so the ratio of the larger perimeter to the smaller is ...

... √(25/4) = 5/2
