Answer:

8x-8

Step-by-step explan:

opposite sides are equal in rectangle .

3x-2+3x-2=6x-4

x+6+x+6=2x+12

were gonna simplify now

6x is positive and 2x is positive. positive + positive = +

so 6x +2x+8x

-4 has a minus sign before it so its negative

+12 has a plus before it so its positive

negative + positive = -

so p=8x-12-4

so p=8x-8

Answer:

2(3x-2)+2(x+6)=perimeter=8x+8

Step-by-step explanation:

2(3x-2)=6x-4

2(x+6)=2x+12

6×-4+2x+12 simplify

8x+8
