first thanks my answer please

Answer 2

Answer:

10 - Nope

11 - 12 , 19

Step-by-step explanation:

10)

Not probably ,

Let sides of two rectangles be ( 6 , 6 ) & ( 3 , 12 )

area = 6 x 6 = 36 = 3 x 12

but perimeter =

2 ( 6 + 6 ) = 24

2 ( 3 + 12 ) = 30

24 ≠ 30

11)

let numbers be x , y

x = 7 + y

Given eq. :

4y + 5x = 143

Substituting x as ( 7 + y ) , we get :

4y + 5 ( 7 + y ) = 143

4y + 35 + 5y = 143

9y = 143 - 35

y = 108 / 9

y = 12

x = 19 ( 12 + 7 )
