Lets assume:
Width=x
Length=x+30
2x+2(x+30)=340
2x+2x+60=340
4x+60=340
4x=280
x=70
Plugging x in:
Width=70
Length=100
$235.94 - 80 = 155.94
155.94 ÷ 25.99 = 6

Answer:
Step-by-step explanation:
y = - 5/6 x + 1
y = mx + b m: slope b: y intercept
point (6 , -4) x = 6 y = -4
b = y - mx = -4 - ((-5/6) x 6) = - 4 + 5 = 1
equation: y = - 5/6 x + 1
