Ok, since the ice rink is a square (which has equal sides) if you multiply 404 times four because a square has 4 sides which is equal to 1616 the perimiter is 1616 sqf
404*4= 1616 p= 1616sq
Because you can have a negative inside the absolute value so even if it is inside the absolute value of -3 will come out as 3.
You need PEMDAS
do 3·6 and then 12/6
when you subtract the product and quoetient you get 16 for the answer
6 over negative 10, because you just multiply the numerator and denominator by 2
2/3x + 4 = 7
-4 -4
4 cancels out.
2/3x = 3
x 3 x3
6/3 = 2x = 9
/2 /2
2 cancels out.
x = 9/2 = 4.5
