Area is 6000 yd2
LW = 6000
field must be 40 yards longer than its width
L = W + 40
Replace L with W+40 in 1st equation to solve for Width
(W+40)(W) = 6000
W2 + 40W - 6000 = 0
This is a quadratic but is factorable
Factors of -6000 that add to 40 are (100)(-60)
(W+100)(W-60) = 0
W = -100 or W = 60
Since the width will not be negative discard -100
The width is 60 yards
Length is W+40 = 100 yards

Step-by-step explanation:

Answer:
-2.5 degrees
Step-by-step explanation:
The temperature decreased 18.5 degrees F in 7.4 hours.
-
-18.5/7.4 = -2.5 degrees F
The average change in temperature over the course of 7.4 hours is -2.5 degrees F.
