Respuesta :

i do not know how to show the working out but its 4+6+6

Answer:

The perimeter of PQR is 17.

Step-by-step explanation:

The work for this problem is below

(3y-2) = (y+4)

+2         +2

3y = y+6

-y     -y

2y = 6

y = 3

then you insert the value of y into (3y-2) which gives you (9-2) which is equivalent to 7.

all you have to do now is add the values of the sides which will give you the perimeter.

4+6+7=17

Hence, the perimeter is 17.

You're welcome :)
