Find the perimeter of the quadrilateral
Stolb23 [73]

To find perimeter, all you need to do is add each side of the shape together. In this case you have a quadrilateral. Since you did not attach a picture of the quadrilateral, I cannot give you the exact answer that you are looking for. But, I do know that you will have 4 numbers. Simply add them up and the sum will be your perimeter.

Which property is shown below?
ElenaW [278]

Answer:

C

Step-by-step explanation:

5+2y+3z=5+3z+2yA

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.

5+3z+2yA=5+2y+3z

Resta 5 en los dos lados.

3z+2yA=5+2y+3z−5

Resta 5 de 5 para obtener 0.

3z+2yA=2y+3z

Resta 3z en los dos lados.

2yA=2y+3z−3z

Combina 3z y −3z para obtener 0.

2yA=2y

Anula 2 en ambos lados.

yA=y

Divide los dos lados por y.

y

yA

​

=  

y

y

​

 

Al dividir por y, se deshace la multiplicación por y.

A=  

y

y

​

 

Divide y por y.

A=1
