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
Answer:
around 2.31
Step-by-step explanation:
because you will get 2.307 if you put it in a calculator then you can round it to 2.31
Mass divided by volume = density... I dont know the exact answer but i hope this helps
Answer is 24p^2 - 6
you get this because you are suppose to use foil
4p x 6p
4p x -3
2 x 6p
2 x -3
when u do all that you get
24p^2 - 12p + 12p -6
combine like terms you get 24p^2 - 6
