Answer:

f(-4) is basically just saying that you need to use the function given while x = -4.

The function given:

f(x) = -8(5-x)

We see that f(-4) means that x has to be -4, so we can substitute it in:

f(-4) = -8(5-(-4))

f(-4) = -8(9)

f(-4) = -72

Therefore, f(-4) is -72.

Hi There,

We Know:

Total Perimeter = 450 feet

Length is 2 times the width.

Length = 150

Width = 75

75 x 2 = 150

150 + 150 + 75 + 75 = 450

Answer:

Length = 150 feet.

Width = 75 feet.
