Using the distance formula we can determine the perimeter of PQR.
Distance formula: d=√(x-x1)^2+(y-y1)^2
distance of PR: √(-2+2)^2+(9+3)^2= 12
distance of QR: √(7+2)^2+(-3+3)^2=9
distance of PQ: √(7+2)^2+(-3-9)^2= 15
Perimeter: 12+9+15=36
?? I don’t really get it, what should I do.
Answer:
The answer is the forth one , Y-8+2⩽-2+2
Answer: 39
Step-by-step explanation:
2x+17-17=95-17 so 2x=78 if you divide both sides by two you will find x=39
