Answer:

AB=16

BC=15

AC=12

PQ=12

QR=12

PR=19

Step-by-step explanation:

well you know that the perimeter is the sum of all sides

so we have

[tex](2x)+(2x+4)+(2x+3)=(2x)+(2x)+(3x+1)\\\\2x+2x+4+2x+3=2x+2x+3x+1\\\\(2x+2x+2x)+(4+3)=(2x+2x+3x)+(1)\\\\6x+7=7x+1\\\\6x+7-1=7x\\\\6x+6=7x\\\\6=7x-6x\\\\x=6[/tex]

so the sides are:

[tex]AB=2x+4=2(6)+4=12+4=16\\\\AB=16[/tex]

[tex]BC=2x+3=2x+4-1=16-1=15\\\\BC=15[/tex]

[tex]AC=2x=2(6)=12\\\\AC=12[/tex]

[tex]PQ=2x=12\\\\PQ=12[/tex]

[tex]QR=2x=12\\\\QR=12[/tex]

[tex]PR=3x+1=3(6)+1=18+1=19\\\\PR=19[/tex]

So there you are.
