X is the length
y is the width
2x+2y=66
x-y=15
multiply the second equation by 2 (elimination)
2x-2y=30
add the equations together
4x=96
x=24
Plug this in to one of the original equations
24-y=15
the width is 9
Answer: A
Same as before, the functions are the same.
The first function is used for x ≤ 1, because of the closed circle.
The second function is used for x > 1, because of the open circle.
Split it up
small square on top with side legnths s and s
big squaer with legnth and width 5s and 3s
area=legnth times width
total area=5s*3s+s*s=15s^2+s^2=16s^2
toatl area=600
600=16s^2
divide both sides by 16
37.5=s^2
squer root both sides6.12372
tenth
6.1 mm is s
s=6.1mm
