6-1 s
2s + b = 36
b + 9 = 8
Option
O Option 2
2b + 8 = 36
s+ 9b
25+ b = 36
s+9=b

Which of the following linear systems models this situation? A rectangular
field is 35 m longer than it is wide. The length of the fence around the
perimeter of the field is 290 m.
1 + 35 = w
21 + 2w = 290
I = w + 35
21 + 2w = 290
Option 1
Option 2
Op 3 I= w+ 35, l+w=290 op 4 l=w = +35, lw=290 1 point
