Circumference is the length of the <em>edge</em> of a shape
Area is the <em>space</em> it takes up in total
Step-by-step explanation:
Since we are walking <em>around</em> the lake and not trying to figure out how much <em>space</em> it is taking up, we would be dealing with circumference in this case.
if it is solution point (4, –2) must satisfy both equations (1) –3x – 2y = –8-->-3*4-2*(-2)=-8 -12+4=-8 then-->-8=-8 ok (2) y = 2x – 5 -2=2*4-5=3---------->-2 is not 3
the point (4, –2) is not solution of the system of equations
