11 teams because

where we find x to be 11.
Try dividing both sides by 2.
Hope i helped :)
(It's kinda cool, because by dividing both sides by 2 we get !<3u :)
Let one length be x and the other be y
x + x + y + y = 440
2x + 2y = 440
Divide by 2 through ...
x + y = 220
y = 220 - x
Area = xy
Area = x(220 -x) = 220x -

Given that that max length of x will be -b/2a
a = -1 b = 220
x =

= 110
x = 110
y = 220 - 110 = 110
Therefore max area = 110 x 110 = 12100 square yards
3x + 4 cannot be negative because of the square root so
3x + 4 >= 0 and x >= -4/3 This is the domain (answer)
The range-
when x = -4/3 y = -5 The range is y>= -5 answer
In interval notation domain = [-4/3, ∞) and range = [-5, ∞)
