Answer:

solution: (x,y) <= (1.5,12)

Step-by-step explanation:

Given

PQ=QR

therefore, (2x+7)=[(y+8)/2]

therefore, 4x+14=y+8

therefore, 4x-y=-6......(1)

now perimeter<=60

PQ+PR+QR <=60

therefore, (2x+7) + [(y+8)/2] + 10 <=60

therefore, 4x+y+42<=60

therefore, 4x+y<=18....(2)

by solving ...(1) & (2)

we get x<=(3/2) OR x<=1.5

& y<=12

solution: (x,y) <= (1.5,12)

I hope u like the solution

please like and comment it
